Description

W celu nadania polysku odbitkom fo¬ tograficznym wykonanym na papierze zelatynowym, lub w celu zmatowania tych¬ ze, nakladamy je po zmoczeniu na szkla¬ na, gumowa, celuloidowa lub tym podobna plyte polerowana lub zmatowana, doci¬ skajac mocno do podloza, wskutek czego po calkowitem wyschnieciu odbitki otrzy¬ muja polysk, wzglednie zostaja zmatowane.Sposób ten jednak posiada pewne nie¬ dogodnosci: Do pracy z wiekszemi ilosciami odbi¬ tek niezbedne sa obszerne, pozbawione kurzu, dokladnie przewietrzane suszarnie, wyposazone w odpowiednie podstawki, sluzace do suszenia odbitek; jednoczesnie tez nalezy uwazac, aby temperatura nie wzrastala zbyt szybko, gdyz obrzeza od¬ bitek scisnietych, wysychajac przedwcze¬ snie, powoduja stopniowe odskakiwanie wierzchniej pofwloki (znane zjawisko u- jemne, zdarzajace sie w odbitkach o znacz¬ nym polysku).Przecietny czas suszenia wynosi okolo 8 godzin, wskutek czego na jednem podlo¬ zu mozna dokonac jednego tylko suszenia przez dzien i jednego przez noc, tak, iz w ciagu doby otrzymujemy dwie odbitki.Aby umozliwic szybkie suszenie, uni¬ kajac przytem wynikajacych stad niedo¬ godnosci, postepujemy, stosownie do wy¬ nalazku, w sposób nastepujacy: Na polerowana powierzchnie plyty szklanej A (patrz rysunek) nakladamy,Sfc l jak zwykle, zmoczona odbitke B, Na te ostatnia nakladamy opisana ponizej suszke, poczem na nia nakladamy druga plyte szklana, z nalozonemi obustronnie odbitkami B1 i fi2, poczem znów suszke C i tak dalej okolo 30 warstw. Wreszcie na wierzch nakladamy plyte P obciazona cie- zairem G. Sriszlka1 przepojona sola higjro- skopijna wchlania chciwie wilgoc, znajduja¬ ca sie w obitkach i wysusza je szybko. Czas suszenia wynosi okolo 45 minut, wskutek czego na jednem podlozu mozna wysuszyc dziennie okolo dziesieciu serji odbitek.Pontewaz óSjbitki podczas suszenia sa sprasowanej wiec przedwczesne stopnio¬ we zwijanie sie obrzezy jest niemozliwe.Suszenia mozna dokonywac w jakiem- kolwiek badz pomieszczeniu, nawet chlod- nem i wilgotnem. Suszki po uzyciu mozna wysuszyc i uzyc ponownie dowolna ilosc razy.Do przeprowadzenia sposobu uzywa¬ my suszek z tworzywa posiadajacego zdolnosc pochlaniania (pape, filc, sukno i t. d.), które przepajamy sola h:\groskopij- na, np. chlorkiem wapnia. Suszki te z obu stron zaopatrujemy w powloke ochrania¬ jaca, np. papierowa, plócienna i t. d. PLIn order to give a gloss to the photographic prints made on gelatine paper, or to dull them, we apply them after wetting to glass, rubber, celluloid or the like polished or matted plate, pressing firmly against the substrate, thereby after complete drying, the prints gain a gloss or are dulled, but this method has some disadvantages: To work with large amounts of prints, you need spacious, dust-free, thoroughly ventilated dryers equipped with appropriate stands for drying. ; at the same time, care should be taken that the temperature does not rise too quickly, as the edges of the compressed sheets dry prematurely cause a gradual detachment of the top fleece (a known negative phenomenon that occurs in highly glossy prints). is about 8 hours, so that one substrate can only be dried one day and one overnight, so that we get two prints a day. In order to allow for quick drying, thus avoiding the consequent inconveniences, we proceed , according to the invention, as follows: On the polished surface of the glass plate A (see figure), apply, Sfc l as usual, the wet print B, On the latter, put the dryer described below, then put the second glass plate on it, with the both sides with prints B1 and fi2, then drying C again and so on, about 30 layers. Finally, on top we put a plate P loaded with G. Sriszlka1, soaked with hygroscopic salt, it greedily absorbs moisture, found in the upholstery and dries them quickly. The drying time is about 45 minutes, which means that on a single substrate it is possible to dry about ten series of prints per day. Because the seeds are pressed during drying, so premature gradual curling of the rim is impossible. Drying can be done in any or in the room, even cool. dry and moist. After use, the driers can be dried and reused as many times as needed. To carry out the process, we use driers made of a material with an absorbing ability (paper, felt, cloth, etc.), infused with h: \ groscopic salt, eg with calcium chloride. These dryers are provided with a protective coating on both sides, e.g. paper, linen, etc.
