Description

Register keeping device

and method of using it Description The invention relates to a device for registering for the purpose of visual determination the correct arrangement of the print on a printed product, in the print and Copy industry, it is always the task of the operator to write or To arrange image field on the product to be printed or copied so that the finished product offers the best possible appearance. At the operator it is usually the printer. In practice, he sets up the printing press for one operation and prints a first copy, which is a test print or proof referred to as. With this he goes to a table where measurements are taken to see if there are any more on the press before the print run Setup work to be done or not.

Usually a light table, tear strips and rulers are used for this used to determine if and what corrections need to be made to to get a better print product. The light table is a large table with a glass top and a light source underneath, which shines through the glass plate and the paper to make the printer's job easier. Because of the size of this table, it is commonly used by several printers and stands in a special room separate from the press room.

The invention provides an apparatus for registering which makes it possible to quickly determine visually whether and which Corrections to a proof must be made in order to obtain a satisfactory one To get edition pressure. The device is space-saving, light and transportable, so that the printer can use them without leaving his desk. Of the The object of the invention is to enable the necessary corrections to be determined, without the use of other equipment such as work tables or tear rails have to.

The device has a transparent cover sheet with markings on it are attached, which serve to ensure the correct arrangement of the print on the underlying Determine the pressure side when the pressure is facing the cover sheet and the test sheet has been put in the right position. Since the cover sheet corresponds to the Print side lets the existing pressure show through, the degree of any deviation between the markings on the cover sheet and the Pressure can be determined when it is in the correct position. To the device may also include a spacer to separate the cover sheet from the one below To keep the surface separate on which the pressure is placed. Preferably the spacer serves as a reference or guide part on which the edge of the Contact pressure is brought to the facility when the markings on the cover sheet Use is made; such a reference or guide part can, however, both can be used with and without spacers.

Appropriately, the cover sheet is attached to the spacer, the in turn is attached to a base that supports the pressure serves.

An embodiment of the invention is shown schematically below with reference to Drawings explained in more detail. It shows: FIG. 1 the top view of an inventive Contraption; 2 shows the device when a pressure page is inserted; Fig. 3 a Front view of the device when inserting an envelope; Fig. 4 is an exploded view Oblique view of the device; FIG. 5 shows section 5-5 in FIG. 1; FIG. and FIGS. 6 to 8 partial representations of the device with pressure pages arranged therein for determination of registration.

In Fig. 1 is an embodiment of the invention in the form of the device 18 shown, to which a base in the form of the base 20, a cover sheet 22 with markings 24 and a reference and guide part 26 for the markings 24 belong.

A sample can be placed between the cover sheet 22 and the base 20 or arrange pressure on the guide 26 and the corresponding markings 24 is aligned in order to make the necessary corrections based on the pressure present on it to investigate; the term "print" or "set" includes all on characters available for printing, including images, letters or others Marks regardless of the way they were made.

Generally, both pad 20 and sheet 22 are of rectangular shape; the base 20 has an upper edge 38 and a lower edge 30 and left and right side edges 33 and 34, respectively, and the topsheet 22 faces corresponding upper and lower edges 36 and 38 as well as left and right side edges 35 and 32 respectively.

The base 20 and the cover sheet 22 are preferably around substantially plane-parallel rectangles, which are essentially one another cover. Usually they are flexible with one another near one edge connected, with the lower edge 28 of the sheet 22 on the lower edge 30 of the pad 20 and the right edge 32 of the sheet 22 on the right edge 34 of the pad 20 hits.

In embodiments where the top edge 36 of the sheet 22 does not extend to the upper edge 38 of the base 20, the upper edge 36 of sheet 22 as a guide for marking, folding, punching, etc. of proof sheets and the pad 20 is used to support the workpiece, especially where Markings should be made against folds, holes, etc.

The markings 24 are generally located in a marking area 27, which is arranged at a distance from a reference or guide part 26. The part 26 expediently runs on the left edge of the marking area 27 and is used as the zero and baseline for the markings 24, which act as position symbols to serve.

According to FIG. 1, the device 18 can serve as a handle Section 40 to the left of the marking area 27.

The left edge 33 of the pad 20 can become the handle section as well as the area immediately to the right of it.

According to FIG. 1, on the sheet 22 immediately to the left of the marking area 27 a cover 42 may be present. This is preferably one rectangular strip of material which rests on the sheet 22 and the guide part 26.

The cover strip 42 helps secure the sheet 22 in place on the pad 20. Usually the cover strip 42 is used as a handle Serving section 40 and the marking area 27 are arranged. In some cases For example, the cover strip 42 may form part of the handle portion 40.

There are a number of different markings 24 on the sheet 22 appropriate. The sheet shown in Fig. 1 is primarily for use in Connection to workpieces in the form of sheets of paper in the format 8 1/2 x 11 inches (about 216 x 280 mm) and marked by business envelopes, but the markings can be 24 also in a different scale for other types of printing and paper formats or for other systems of measurement, e.g. the metric system, may be implemented.

A network of lines 44 can be used for the markings 24 on the sheet 22 crossing, evenly spaced, parallel verticals Lines 46 and equally spaced, parallel horizontal lines 48 belong. Because of these uniform distances, the line network 44, which is preferably covers the entire sheet 22 in the marking area, usually in conjunction with other markings 24, are used to make the necessary registration corrections to investigate. Preferably the markings are blue, but any other can be used Color or color combination can be used.

In the illustrated embodiment, the distance is between the lines 1/4 inch (about 6.35 mm).

A centering scale 50 for central arrangement can be attached to the markings 24 of the title block on the proof, preferably near the top 36 of the sheet is arranged and parallel to the horizontal line 48 of the network of lines 44 runs. For a proof in the format of 8 1/2 x 11 inches, the scale starts at 50 on guide member 26 marked for 4 1/4 inches (about 108 mm) and extends to the right, with the scale first going back from 4 1/4 to 0 inches and then increases from 0 to 4 1/4 inches. The centering scale shown applies to one pressure of the format 8 1/2 x 11 inches, with the zero mark serving as the centering mark, if a longitudinal edge of the paper sheet on the guide part 26 shown in FIG. 5 is present.

A marking 51 for alignment can also be used with the markings 24 belonging to the lower edge of the pressure side; this preferably runs on the sheet 22 parallel to its top edge is 36. In the case of the 8 1/2 x 11 inch format, the bottom is Margin marker 51 from top edge 36 of sheet 11 inches. At the When the centering scale 50 is used, the longitudinal edge of the pressure preferably runs parallel to the guide 26 and rests against it, and the lower edge of the pressure runs parallel to the lower side edge marking 51 and rests against it.

Fold markings can be added to the markings 24 made on the sheet 22 52 belong, with the help of which it can be determined whether printed characters or other Representations coincide with a fold line. This facility is used for print products, that are to be folded, e.g. for insertion into an envelope. With the fold marks 52 is usually a pair of parallel lines that define the distance between the upper edge of the sheet 22 and the lower edge mark 51 in three divide almost equal sections.

The markings 24 may include a set of ring hole markings 54, which correspond to the holes that will be punched in the finished printed matter can. Generally, these ring hole markings 54 are on the sheet 22 between its upper edge and the marking 51 for the lower edge distributed and in one Distance from the reference and guide part 26 attached as with a normal three-ring binder. This allows the printer to determine if any part of the print is being punched will fall out and he can make the necessary changes. At a Embodiment, the hole marks can actually be holes in the sheet 22 be executed.

The markings 24 may include markings 56 that correspond to the correct one Placement of postal signs are used. This preferably includes a marking 56 for the edge of a response part that is parallel to one side of the sheet 22. The marking expediently extends at right angles for the edge of the response part to the guide member 26 so that when the top edge of an envelope or an Map or other printed matter on part 26 and the corresponding side edge rests against the marking for the edge of the response part, the postal markings 56 of the sheet 22 take up the correct position on the printed product.

Within the framework of the marking 24, a measuring scale 58 can be placed on the sheet 22 be printed, which is preferably parallel to the right edge 32 of the sheet 22 and runs near it.

Of course, other appropriate markings can also be present, E.g., not shown markings for the address on a printed matter which is in a window envelope should be inserted so that the address appears in the window.

In the embodiment according to FIG. 2, the test or proof can be inserted by holding the register retainer 18, e.g., by grasping it of the handle portion 40 with the Hand, and then the right edge of sheet 22 lifts so that the pressure with the cover sheet facing the print side can be introduced, its one side edge on the guide part 26 and its lower edge comes to rest against the marking 51 for the lower edge.

In the embodiment of FIG. 3 can be a similar way Insert the envelope into the device 18 with its one edge on the guide part 26 and the marking on the envelope on the corresponding Post mark marks 56 are aligned. Now the sheet 22 is with the Surface of the pad 20 brought to register, so that the postmark marks 56 are aligned as closely as possible with the postage indicia that the Printer attached to the sample print. Necessary corrections can then be based on of the deviations between the markings 24 on the sheet 22 and the markings can be determined on the test print.

Fig. 4 shows how the cover strip 42, the sheet 22, the guide member 26 and the base 20 are glued together to form a unit in order to create the register holding device 18 to form. A first strip 60 of double-sided adhesive tape is applied the top of the pad 20 applied, parallel to its left edge, however far enough away from this to the section used for handling 40 release. The reference and guide part 26, which is preferably made of rigid material in the form of a rectangular strip with approximately the same dimensions as the first Adhesive tape strip 60 is now applied to this so that it is essentially covers with it. In a similar way, a second one is then added Strips 62 of double-sided adhesive tape with approximately the same dimensions how the guide part 26 is placed on this and essentially coincides with it brought. Now the sheet 22 is placed on the base 20, in such a way that the right edge of the sheet 22 to the right Edge 34 of the pad and the lower edge 28 of the sheet 22 extends to the lower edge 30 of the pad 20, the one adjacent to the left edge of the sheet 22 and running parallel to the latter Area applied to the second strip 62 of double-sided adhesive tape so that the markings 24 begin at the right edge of the guide part 26. The further the left edge of the sheet 22 extends over the second strip 62 from both sides the adhesive tape, the stronger the bond. Consequently will be the sheet 22 preferably extend fully to the left edge of the base 20.

In a preferred embodiment, a third strip 64 made of double-sided adhesive tape essentially in coverage with the second one below Strip 62 is applied to sheet 22 and a masking strip is applied as previously described 42 on the third strip of adhesive tape 64 and essentially in register with this upset.

According to FIG. 5, the device 18 has between the base 20 and the sheet 22 with the markings 24 has a guide part 26. This part 26 is used as a spacer as it is thick enough to hold a sheet of paper inside Allowing there are marks on sheet 22 and on the proof sheet but thin enough to provide a true reference line for the markers 24. The guide part 26 plus the adhesive tape is therefore preferably approximately the same thickness a sheet of paper, which is generally about 0.2 to 0.3 mm, and the distance between the sheet 22 and the base 20 is most favorable about 0.25mm. Depending on the type of paper to be used and the desired Coverage of the markings can, however, also be thicker or thinner guide parts 26 can be used.

The cover strip 42 is used in part for decorative purposes.

It also helps keep sheet 22 on base 20 for sure in part because some users attach device 18 to the Grab cover strip 42, and in part because in some embodiments the cover strip 42 itself contributes to the fixing of the sheet 22.

A secure definition of the sheet 22 is because of the necessary registration accuracy he wishes.

The sheet 22 does not need to extend to the left edge of the cover strip 42 to extend, but this also contributes to the secure holding of the sheet 22, because a user of the device 18 is very likely to use the device 18 take hold of its left edge and thereby hold the sheet 22 in its position. As a result, the stress on the sheet 22 at its gluing point is also reduced of the base is reduced, its service life is extended and the accuracy of coverage is increased elevated.

Instead of double-sided adhesive tape, rivets, screws or other fasteners can be used. There is an impression that the Using tape or glue is preferable because these have a larger size Cover surface area and thereby the possibility of changing the position of the Reduce sheet 22 compared to the guide part 26.

The use of a hanging system with the help of rivets, screws or the like, however, adding or replacing prepunched sheets would with minimal Allow alignment problems.

Generally, the sheet 22 is made of glass or plastic.

Preferably, the sheet 22 becomes clearer, more transparent, more flexible Plastic used, e.g. MYLAR, a brand name of E. 1. DuPont deNemours and Co., or TXP, a trademark of Transilwrap Corp. for polyester extrusion. The plastic should be smooth and flexible, but in its flat, planar shape return when it is placed on the pad 20.

The markings 24 may be printed on the sheet 22, however the sheet 22 can also consist of photosensitive material, so that the markings 24 can be transferred to sheet 22 by photographic means and printed.

The base 20 is expediently made of solid, rigid material like wood, plastic or metal. As a result of its rigidity, the base 20 serve as a portable work table and enables better coverage accuracy as a non-rigid base 20. However, one can also be used.

A double-sided adhesive tape is preferably used 3M brand used. However, any double-sided tape can be used that compatible with the material of sheet 22, guide member 26 and pad 20 is.

The guide part 26 can be made of any material.

Plastic is preferably used, but wood, metal can also be used or another suitable material in question. The guide part 26 should preferably form or be provided with a ruler.

When using the device, the test print according to Fig. 2 and 3 introduced into the device 18 by first defining it, for example by grasping it by hand, then lifting one edge of the sheet 22 and removing the To push the test print between the sheet 22 and the base 20 with the other hand, until the desired edge of the test print rests on the guide part 26. Now the sheet 22 is placed on the test print and the latter shifted until the relevant Markings on sheet 22 are aligned as precisely as possible with the sample print.

To use most of the markings 24, the trial or applied pressure in the manner shown in Fig. 2, whereby he is facing up between the cover sheet 22 and the base 20 is pushed. The left edge of the proof is arranged so that it is parallel runs to the reference and guide part 26 and rests against it, while the lower Edge of the pressure runs parallel to the marking 51 for the lower edge of the page and is attached to it.

This arrangement is typical for the use of the centering scale 50, of the fold line marks 52 and the ring hole marks 54. When the sheet 22 is placed on the proof, the relevant investigations regarding the Registration can be made.

If marks are to be specified for postage marks, the proof is expediently inserted according to Fig. 3, i.e. the upper edge of the pressure is on the Guide part 26, and the side edge of the closest to the postal markings The pressure is applied to the marking for the edge of the response part, so that after placement of the cover sheet 22 performed the register retention determinations on the envelope sample print can be.

For the registration and position determination device 18 is a right-handed system has been shown, but a left-handed one can also be used or other system can be used.

In Fig. 6 the edge of the pressure is set incorrectly, holes fail should be made for stapling, because parts of the print are punched out here. In this particular case, part of the first word of the second line in the punched out left column. As a result, the printer must adjust the left margin so that that this problem is avoided.

Using the scale at the top of the page, the printer can tell that between every two s - right lines 46 the same predetermined distance from bfl «.? iels.; t -; lse 0.25 inch (about 6.35mm) according to FIG. 6 is present. Through a Therefore, looking at Fig. 6, the printer can immediately determine that the margin is at least 1/8 inch (about 3.175 mm) must be widened to allow for the punching out of parts of the word to avoid when punching holes in the paper for binding in a folder.

In FIG. 7 the pressure was applied in the same way as in FIG. Here the printer would like to see for himself whether the title "Almonds Delivered to Your Door Naturally "is written in the middle of the sheet. By looking at the centering scale 50 he can easily determine whether the title is correctly centered or not. If the title is off-center, the printer can use the scale division of the line network 44 quickly determine how far and in which direction the title must be moved.

In Fig. 8, the printer can see that the fold line 52 along the the top of the line "How should pension assets be invested. As a result the printer will move the font slightly to avoid the problem of that a line coincides with a fold line 52. Such a shift is bearing contribute to a better appearance of the finished product.

The pressure can with the help of the upper edge 36 of the sheet 22 with Lines or markings for the perforation can be provided.

Here, the pad 20 itself serves as a support for the pressure, while the mark is being applied.
