An authorizing card having at least on one side a first area (1) printed with visible ink (5, 5') and a second area (2) coated with thermosensitive ink (6, 6'), the second area (2) costed with thermosensitive ink (6, 6') being provided to be printed with alphanumeric data (7, 8) corresponding to the value of the card by the thermoprinting means of a cash register, characterized in that the first area (1) printed with visible ink (5, 5') is also coated with thermosensitive ink (6', 6").

Description

Die Erfindung bezieht sich auf eine Berechtigungskarte, die zumindest auf einer Seite einen mit sichtbarer Farbe bedruckten ersten Bereich und einen zweiten, mit thermosensitiver Farbe beschichteten Bereich aufweist, wobei der zweite, mit thermosensitiver Farbe beschichtete Bereich zum Bedrucken mit dem Wert der Karte entsprechenden alphanumerischen Daten durch eine Thermodruckeinrichtung einer Registrierkasse vorgesehen ist.The invention relates to an authorization card which has at least on one side a first area printed with visible color and a second area coated with thermosensitive color, the second area coated with thermosensitive color for printing with alphanumeric data corresponding to the value of the card is provided by a thermal printing device of a cash register.

Es sind Wintersportkarten bekannt, die bis auf ein freies Feld auf einer Seite am vorderen Rand der Karte beidseitig mit unveränderbaren Daten bedruckt sind, beispielsweisemit Informationen über die betreffenden Bergbahnen und Lifte, für die die Karte gültig ist, wie Namen und Länge derselben, der von ihnen überwundene Höhenunterschied, Panoramakarten, Beförderungsbedingungen usw.Winter sports cards are known which, with the exception of a free field on one side at the front edge of the card, are printed on both sides with unchangeable data, for example with information about the relevant cable cars and lifts for which the card is valid, such as the name and length of the card, from height difference overcome, panorama maps, conditions of carriage, etc.

Das freie Feld wird dann beim Kauf der bekannten Karte von dem Farbdruckwerk der Registrierkasse mit veränderbaren Daten versehen, und zwar mit Daten, die den Wert der Karte bestimmen, also beispielsweise mit einem "E" für Erwachsene, einer "3" für eine Gültigkeitsdauer der Karte von drei Tagen, und mit anderen vom Wert der Karte unabhängigen Daten, wie z. B. dem Datum des Kaufs der Karte oder einer fortlaufenden Zahl.The free field is then provided with changeable data by the cash register's color printing unit when the known card is purchased, namely data which determine the value of the card, for example with an "E" for adults, a "3" for a period of validity of the card Card of three days, and with other data independent of the value of the card, such as B. the date of purchase of the card or a sequential number.

Die Farhdruckwerks dieser Registrierkassen sind jedoch mit einer Reihe von Nachteilen behaftet. So müssen sie häufig gewartet werden (z. B. zun Nachfüllen von Farbe oder zur Reinigung). Ferner weisen sie einen relativ hohen Verschlein und damit eine entsprechend hohe Reparaturanfälligkeit bzw. niedrige Lebensdauer auf.However, the cash registers of these cash registers have a number of disadvantages. So they have to be serviced frequently (e.g. for refilling paint or for cleaning). Furthermore, they have a relatively high wear and thus a correspondingly high susceptibility to repairs or a short service life.

Es sind deshalb auch Wintersportkarten bekannt, die mit einer Thermodruckeinrichtung bedruckbar sind.Winter sports cards are therefore also known which can be printed with a thermal printing device.

Dazu wird auf konventionell mit sichtbarer Farbe bedruckten Kartonbögen ein Streifen aus thermosensitiven Papier an den Randbereich aufgeklebt, der von der Thermodruckeinrichtung der Registrierkasse bedruckt wird.For this purpose, a strip of thermosensitive paper is glued to the edge area on conventionally printed cardboard sheets, which is printed by the thermal printing device of the cash register.

Nachteilig bei diesen Verfahren ist der hohe arbeitsaufwand für das aufbringen des thermosensitiven Papierstreifens auf den Kartonbogen. Insbesondere ergaben sich Schwierigkeiten bei der Positionierung der Streifen. Auch zerrissen die Streifen bein aufkleben häufig. Darüber hinaus weisen die so hergestellten Karten in Bereich des Streifens eine größere Dicke auf, so daß, wenn sie als Stapel in der Registierkasse vorliegen, sie von der erforderlichen Planlage abweichen, also Probleme bei der automatischen Vereinzelung der Karten in der Registrierkasse ergeben.A disadvantage of these processes is the high amount of work involved in applying the thermosensitive paper strip to the cardboard sheet. In particular, there were difficulties in positioning the strips. The strips are often torn apart. In addition, the cards produced in this way have a greater thickness in the region of the strip, so that if they are present as a stack in the cash register, they deviate from the required flatness, that is to say there are problems with the automatic separation of the cards in the cash register.

Vor allem aber haben die mit einem thermosensitiven Papierstreifen versehenen Karten zu zunächst unerklärlichen Kassenfehlbeträgen in den Registrierkassen geführt. Wird eine solche Karte von der Registrier kasse ausgegeben, ohne daß der thermosensitive Papierstreifen von der Thermosdruckeinrichtung bedruckt worden ist, so ist die Ursache für das Nichtbedrucken des thermosensitiven Papierstreifens für die Kassenbedienungsperson nicht erkennbar. D. h. die Kassenbedienungsperson weiß nicht, ob das Nichtbedrucken des thermosensitiven Streifens an einer unvollständigen Bedienung der Registrierkasse lag, einer kurzzeitigen Stromunterbrechung oder dergleichen. Sie wird dann den Kartenausgabevorgang wiederholen. Es hat sich jedoch herausgestellt, daß eine Ursache auch darin bestehen kann, daß die Thermodruckeinrichtung den Druckvorgang zwar ausführt, der thermosensitive Farbstreifen der Karte während des Druckvorgangs gegenüber der Thermodruckeinrichtung jedoch nicht richtig positioniert ist, so daß die Druckeinrichtung den Teil der Karte ohne thermosensitiven Farbstreifen beaufschlagt. Auch in einem solchen Fall wird die Kassenbedienungsperson den Kartenausgabevorgang wiederholen. Dies hat aber zur Folge, daß die Registrierkasse die nur einmal verkaufte Karte zweimal registriert und damit Kassenfehlbeträge auftreten.Above all, however, the cards provided with a thermosensitive paper strip have led to inexplicable cash shortages in the cash registers. If such a card is issued by the cash register without the thermosensitive paper strip being printed by the thermal printing device, the cause for the non-printing of the thermosensitive paper strip is not recognizable to the cash register operator. I.e. the cash register operator does not know whether the non-printing of the thermosensitive strip was due to incomplete control of the cash register, a brief power cut or the like. It will then repeat the card issuing process. It has been found, however, that a cause can also be that the thermal printing device carries out the printing process, but the thermosensitive color strip of the card is not correctly positioned relative to the thermal printing device during the printing process, so that the printing device has the part of the card without thermosensitive color strips acted upon. Even in such a case, the till operator will repeat the card issuing process. However, this has the consequence that the cash register registers the card that was sold only once, and thus cash deficits occur.

Der in den Ansprüchen gekennzeichneten Erfindung liegt die Aufgabe zugrunde, eine mit einer Thermodruckeinrichtung einer Registrierkasse bedruckbare Berechtigungskarte anzugeben, mit der verhindert wird, daß Kassenfehlbeträge aufgrund einer nicht richtigen positionierung der Karte gegenüber der Thermodruckeinrichtung auftreten, die jedoch wasser- und abriebfest mit sichtbarer Farbe bedruckt ist und die sich gestapelt automatisch ohne weiteres vereinzeln läßt.The object of the invention, which is characterized in the claims, is to provide an authorization card which can be printed with a thermal printing device of a cash register, with which it is prevented that cash deficits occur due to incorrect positioning of the card in relation to the thermal printing device, but which are printed with visible ink in a water and abrasion resistant manner is and which can be stacked automatically separated easily.

Nachstehend sind zwei Ausführungsformen der erfindungsgemäßen Karte zusammen mit dem jeweiligen Herstellungsverfahren anhand der Zeichnung näher erläutert. Darin zeigen:

  • Figur 1 eine Draufsicht auf eine erste Ausführungsform der erfindungsgemäßen Karte in Form einer Wintersport-Tageskarte.
  • Figuren 2 und 3 jeweils schematisch und in vergrößerter teilweiser Wiedergabe einen Schnitt entlang der Linie II-II bzw. 111-111 nach Figur 1; und
  • Figur 4 schematisch und in vergrößerter teilweiser Wiedergabe einen Schnitt durch eine zweite Ausführungsform der erfindungsgemäßen Karte.
Two embodiments of the card according to the invention are explained in more detail below together with the respective production method with reference to the drawing. In it show:
  • Figure 1 is a plan view of a first embodiment of the card according to the invention in the form of a winter sports day ticket.
  • Figures 2 and 3 each schematically and in an enlarged partial representation a section along the line II-II and 111-111 of Figure 1; and
  • Figure 4 schematically and in an enlarged partial representation a section through a second embodiment of the card according to the invention.

Gemäß Figur 1 weist die Karte einen mit sichtbarer Farbe 5 bedruckten ersten Bereich 1 und einen mit der sichtbaren Farbe nicht bedruckten zweiten Bereich 2 auf, der als streifenförmiges Feld am unteren Rand, der oben mit einer Befestigungsöse 3 versehenen Karte ausgebildet ist.According to FIG. 1, the card has a first area 1 printed with visible color 5 and a second area 2 not printed with the visible color, which is designed as a strip-shaped field at the lower edge, the card provided with a fastening eyelet 3 at the top.

Gemäß Figur 2 und 3 weist die Karte einen Träger 4 aus Karton auf.According to Figures 2 and 3, the card has a carrier 4 made of cardboard.

Der mit sichtbarer Farbe 5 bedruckte Kartonbereich 1 weist unveränderbare alphanumerische Daten auf, wie Art der Karte, z. B. Tageskarte, anlagespezifische Informationen, wie eine Panoramakarte mit den Bergbahnen und den Liften, für die die Karte gültig ist usw.The cardboard area 1 printed with visible color 5 has unchangeable alphanumeric data, such as the type of card, e.g. B. Day ticket, system-specific information, such as a panoramic map with the cable cars and lifts, for which the card is valid, etc.

Gemäß Figur 2 ist das mit sichtbarer Farbe 5 nicht bedruckte streifenförmige Feld 2 mit thermosensitiver Farbe 6 vollflächig bedruckt. Dabei ist gemäß Figur 1 das mit thermosensitiver Farbeversehene Feld 2 der Karte bereits von der Thermodruckeinrichtung der Registrierkasse mit den veränderbaren alphanumerischen Daten bedruckt worden.According to FIG. 2, the strip-shaped field 2 that is not printed with visible ink 5 is printed over the entire area with thermosensitive ink 6. 1, the thermo-sensitive color field 2 of the card has already been printed with the changeable alphanumeric data by the thermal printing device of the cash register.

Die veränderbaren Daten bestehen aus den alphanumerischen Daten 7, die den Wert der Karte bestimmen, z. B. ""EE", d. h. Einheimischer Erwachsener, und alphanumerischen Daten 8, die wertunabhängig sind z. B. das Datum des Tages, für den die Tageskarte gilt.The changeable data consist of the alphanumeric data 7 which determine the value of the card, e.g. B. "" EE ", i.e. native adult, and alphanumeric data 8, which are independent of value, e.g. the date of the day for which the day ticket is valid.

Der mit sichtbarer Farbe 5 bedruckte Bereich 1 ist ferner mit einem Raster aus Punkten 6' mit thermosensitiver Farbe bedruckt worden. Das punktförmige Raster kann auf der gesamten Breite des Bereichs 1 vorgesehen sein oder lediglich in einem Bereich, der sich in Bewegungsrichtung der Karte in der Registrierkasse erstreckt und eine Breite aufweist, die der Breite der von der Thermodruckeinrichtung der Registrierkasse, gedruckten Daten 7, 8 entspricht, die den Wert der Karte bestimmen.The area 1 printed with visible ink 5 has also been printed with a grid of dots 6 'with thermosensitive ink. The punctiform grid can be provided over the entire width of the area 1 or only in an area that extends in the direction of movement of the card in the cash register and has a width that corresponds to the width of the data 7, 8 printed by the thermal printing device of the cash register that determine the value of the card.

Das Raster aus den Punkten 6 ist in Figur 1 sichtbar dargestellt. Tatsächlich können die einzelnen Punkte 6' des Rasters jedoch so klein gewählt werden, daß sie mit dem freien Auge praktisch nicht mehr erkennbar sind. Der Abstand der einzelnen Punkte 6' des Rasters voneinander wird dabei so gewählt, daß die alphanumerischen Daten 7, die den Wert der Karte bestimmen, gerade noch erkennbar sind, wenn bei Ausgabe der Karte die Thermodruckeinrichtung der Registrierkasse fehlerhafterweise den Bereich 1 und damit die Punkte 6' des Rasters anstelle des streifenförmigen Feldes 2 beaufschlagt.The grid from points 6 is shown in FIG. 1. In fact, however, the individual points 6 'of the grid can be chosen to be so small that they are practically invisible to the naked eye. The distance between the individual points 6 'of the grid is chosen so that the alphanumeric data 7, which determine the value of the card, can just be recognized if the thermal printing device of the cash register erroneously area 1 and thus the points when the card is issued 6 'of the grid instead of the strip-shaped field 2 is applied.

Die Kassenbedienungsperson kann also bei der Ausgabe einer Karte, die von der Thermodruckeinrichtung der Registrierkasse auf dem streifenförmigen Feld 2 nicht bedruckt worden ist, feststellen, ob die Thermodruckeinrichtung und damit die Registrierkasse tätig gewesen sind und zutreffendenfalls die Karten, die von der Thermodruckeinrichtung lediglich auf dem Bereich 1 und damit dem Raster bedruckt worden sind, sammeln und anhand der von dem Raster ablesbaren wertbestimmten Kartendaten 7 in der Registrierkasse auftretenden Fehlbeträge korrigieren.The cash register operator can thus, when issuing a card that has not been printed on by the cash register's thermal printing device on the strip-shaped field 2, determine whether the thermal printing device and thus the cash register have been active and, if applicable, the cards that the thermal printing device only has on the Area 1 and thus the grid have been printed, collect and correct any shortfalls that occur in the cash register using the value-determined card data 7 that can be read from the grid.

Da bei der Ausführungsform gemäß Figur 1 bis 3 der mit thermosensitiver Farbe vollflächig bedruckte Bereich 2 relativ schmal ist, ist eine Schüsselbildung oder ein Verwerfen der Karte verhindert. Da sich andererseits die thermosensitive Farbe auch über den mit sichtbarer Farbe bedruckten Bereich 1 in Form eines Rasters erstreckt, ist eine Planlage der in der Registrierkasse gestapelten Karten gewährleistet.Since, in the embodiment according to FIGS. 1 to 3, the area 2 printed over the entire area with thermosensitive ink is relatively narrow, the formation of a bowl or discarding of the card is prevented. On the other hand, since the thermosensitive ink also extends over the area 1 printed with visible ink in the form of a grid, a flatness of the cards stacked in the cash register is ensured.

Figur 1 stellt eine Schwarzweißabbildung einer ansich farbigen Karte dar.Figure 1 shows a black and white image of a card in itself colored.

In Figur 1 sind daher die Punkte 6"des Rasters nur an den weißen Flächen des Bereichs 1 deutlich erkennbar. Tatsächlich sind jedoch die dunklen Flächen des Bereichs 1 farbig, z. B. hellblau, so daß die Punkte6' des Rasters, die beim Bedrucken mit der Thermodruckeinrichtung z. B. schwarz werden, sich kontrastreich abheben.In FIG. 1, therefore, the dots 6 "of the raster can only be clearly recognized on the white areas of area 1. In fact, however, the dark areas of area 1 are colored, for example light blue, so that the dots 6 'of the raster are used during printing with the thermal printing device, e.g. go black, stand out in high contrast.

Das Raster aus den punkten 6' kann auch durch einen vollflächig mit thermosensitiver Farbe bedruckten Abschnitt auf dem ersten Bereich 1 ersetzt sein. Ein solcher Abschnitt kann dann zur thermosensitiven Aufzeichnung weitererDaten herangezogen werden.The grid from the points 6 ′ can also be replaced by a section on the first area 1 that is printed over the entire area with thermosensitive ink. Such a section can then be used for the thermosensitive recording of further data.

Das Bedrucken der Karte gemäß Figur 1 bis 3 mit thermosensitiver Farbe erfolgt vorzugsweise durch Siebdruck. Auch ist ein Bedrucken durch Tiefdruck möglich.The card according to FIGS. 1 to 3 is printed with thermosensitive ink, preferably by screen printing. Printing by gravure is also possible.

Thermosensitive Farben enthalten als Lösungsmittel normalerweise Benzin, das sich schnell verflüchtigt. Beim Siebdruck kommt es dadurch zu einer Hautbildung und damit zu einer Verstopfung des Siebes. Um die Hautbildung zu verhindern, ist versucht worden, der thermosensitiven Farbe die üblichen Verzögerungsmittel für Siebdruck zuzugeben. Es hat sich jedoch gezeigt, daß diese Verzögerungsmittel, z. B. Ketone, zu einer Schwarzfärbung derthernosensitiven Farbe führen.Thermosensitive paints usually contain gasoline as a solvent, which evaporates quickly. With screen printing, this leads to skin formation and thus blockage of the screen. In order to prevent skin formation, attempts have been made to add the usual screen printing retardants to the thermosensitive ink. However, it has been shown that these delay means, e.g. B. ketones, lead to blackening of the thermosensitive color.

Beim Eintrocknen der thermosensitiven Farbe kann jedoch durch Firnis-haltige Zusätze erfolgreich antgegengetreten werden.When the thermosensitive paint dries out, it can be successfully counteracted with varnish-containing additives.

Die in Figur 4 dargestellte Ausführungsform der erfindungsgemäßen Karte unterscheidet sich von derjenigen nach Figur 1 bis 3 im wesentlichen dadurch, daß der Träger 4' aus Kunsstoff besteht, eine bestimmte thermosensitive Farbe 6" vorliegt und neben dem Bereich 2 auch der Bereich 1 vollflächig mit thermosensitiver Farbe 6" beschichtet ist.The embodiment of the card according to the invention shown in FIG. 4 differs from that according to FIGS. 1 to 3 essentially in that the carrier 4 'consists of plastic, a certain thermosensitive color 6 "is present, and in addition to area 2, area 1 also has a full area with thermosensitive Color 6 "is coated.

Dabei wird als Kunststoff für den Träger 4' vorzugsweise Polyvinylchlorid, ABS (Acrylbutadienstyrolcopolymeres) oder Polystyrol verwendet.Polyvinyl chloride, ABS (acrylic butadiene styrene copolymer) or polystyrene is preferably used as the plastic for the carrier 4 '.

Bei Wintersportkarten, bei denen es neben einer hohen Einreißfestigkeit auf eine hohe Kälteschlagfähigkeit ankommt, wird bevorzugt PVC oder ABS eingesetzt, und zwar aus Kostengründen vor allem PVC. Polystyrol kann aufgrund seines höheren Erweichungspunktes jedoch in anderen Fällen bevorzugt sein, insbesondere bei Berechtigungskarten, wie Maut- oder Parkberechtingungkarten, die häufig im Auto aufbewahrt werden und daher mitunter hohen Temperaturen ausgesetzt sind.For winter sports cards, where high tear resistance and high cold impact resistance are important, PVC or ABS is preferred, especially PVC for cost reasons. However, due to its higher softening point, polystyrene may be preferred in other cases, in particular for authorization cards, such as toll or parking authorization cards, which are often kept in the car and are therefore sometimes exposed to high temperatures.

Die thermosensitive Farbe 6, die auf den Kunststoffträger 4' bei der Ausführungsform nach Figur 4 aufgebracht wird, ist in der deutschen Offenlegungsschrift 28 37 921 im einzelnen beschrieben. Sie besteht im wesentlichen aus einem Farbstoffvorprodukt, einer mit diesem unter Farbbildung reagierenden Entwicklersubstanz sowie einem Paraffin- oser Esterwachs als Bindemittel. Auch kann sie, was bei Wintersportkarten von Bedeutung ist, ein UV-Schutzmittel, wiephenolische Antioxidantien, Octadecyl-3-(3,5-ditert.-butyl-4-hydroxyphenyl)-propionat und dergleichen, enthalten.The thermosensitive paint 6, which is applied to the plastic carrier 4 'in the embodiment according to FIG. 4, is described in detail in German Offenlegungsschrift 28 37 921. It essentially consists of a preliminary dye product, a developer substance which reacts with this to form a color, and a paraffin-ester wax as a binder. It can also contain, which is important for winter sports cards, a UV protective agent, such as phenolic antioxidants, octadecyl 3- (3,5-di-tert-butyl-4-hydroxyphenyl) propionate and the like.

Es ist als überraschend anzusehen, daß die sichtbare Farbe 5' auf dieser einen hohen Wachsanteil aufweisenden thermosensitiven Farbe 6' haftet, und zwar in einem Ausmaß, daß sie selbst den Anforderungen genügt, die an eine Wintersportkarte gestellt werden. D. h. die sichtbare Farbe 5' geht von der Schicht aus thermosensitiver Farbe 6' auch dann nicht ab, wenn sie gegebenenfalls im feuchten Zustand lange Zeit z. B. an der Kleidung des Wintersportlers scheuert.It is to be regarded as surprising that the visible color 5 'adheres to this thermosensitive color 6', which has a high wax content, to an extent that it itself meets the requirements imposed on a winter sports card. I.e. the visible color 5 'does not go off from the layer of thermosensitive color 6' even if it is in the moist state for a long time, for. B. scrubs on the clothes of the winter sportsman.

Das Bedrucken der thermosensitiven Farbschicht 6" mit sichtbarer Farbe erfolgt vorzugsweise durch Offsetdruck, wobei allerdings nicht die herkömmlichen Offsetfarben verwendet werden, sondern oxidativ trocknende Farben.The thermosensitive ink layer 6 ″ is preferably printed with visible ink by offset printing, although it is not the conventional offset inks that are used, but rather oxidatively drying inks.

Weiterhin hat sich ein bestimmtes Verfahren zum Beschichten des Kunststoffträgers 4' mit der thermosensitiven Farbe 6" als besonders vorteilhaft erwiesen. Danach wird der Träger in Bandform zwischen einer Auftragswalze und einer Andruckwalze hindurch bewegt. Die Auftragswalze weist dabei eine profilierte Oberfläche auf, um ihr Flüssigkeitsspeichervermögen zu vergrößern. Zur Profilierung der Oberfläche kann auf die Oberfläche der Auftragswalze ein Draht aufgewickelt sein. Eine entsprechende Auftragsvorrichtung ist beispielsweise in der deutschen Auslegeschrift 21 01 294 beschrieben.Furthermore, a certain method for coating the plastic carrier 4 'with the thermosensitive ink 6 "has proven to be particularly advantageous. The carrier is then moved in strip form between an application roller and a pressure roller. The application roller has a profiled surface in order to increase its liquid storage capacity A wire can be wound onto the surface of the application roller in order to profile the surface, a corresponding application device is described, for example, in German specification 21 01 294.

Als Dispersionsmittel für die aufzutragende thermosensitive Farbe wird auch bei diesem Verfahren Benzin verwendet. Dabei gelingt es mit diesem Verfahren das auf den Kunststoffträger 4' einwirkende Benzin vor seiner Verflüchtigung der Menge und der Einwirkzeit so abzustimmen, daß der Kunststoffträger 4' in einer Weise angelöst wird, die ein einwandfreies Haften der thermosensitiven Farbe 6' an dem Kunststoffträger 4' sicherstellt.Gasoline is also used in this process as a dispersant for the thermosensitive paint to be applied. With this method, it is possible to adjust the gasoline acting on the plastic carrier 4 'before its volatilization of the amount and the contact time so that the plastic carrier 4' is dissolved in a way that the thermosensitive paint 6 'adheres perfectly to the plastic carrier 4'. ensures.

Es hat sich gezeigt, daß manche Kunststoffe harte partikel enthalten, die im Laufe der Zeit zu Beschädigungen der Thermodruckeinrichtung führen können. Derartige Beschädigungen lassen sich beispielsweise verhindern, wenn zumindest auf die Seite des Kunststoffträgers eine dünne Papierschicht kaschiert wird, die mit der thermosensitiven Farbe beschichtet wird. Vorzugsweise wird dazu Kunststoffpapier verwendet. Das Kunststoffpapier kann entweder vollsynthetisch oder teilsynthetisch sein.It has been shown that some plastics contain hard particles that can damage the thermal printing device over time. Such damage can be prevented, for example, if a thin paper layer is laminated onto the side of the plastic carrier, which is coated with the thermosensitive paint. Plastic paper is preferably used for this. The plastic paper can be either fully synthetic or partially synthetic.
