Layout / graphics file

Files created in the next programs are accepted:

- Adobe Illustrator to CS 2.0 version

- Adobe Indesign to CS 2.0 version

- Adobe Photoshop to CS 2.0 version

- CorelDraw up to version 15.0

Files created in other programs can be received upon the coordination of technical issues.

Note:

It is highly undesirable to use effects with transparency in Adobe Illustrator and CorelDRAW !.

PDF file (Composite)

To create such a file, we recommend using Acrobat Distiller v.4.05.

Be sure to transfer the composite file.

Note:

You can not use raster DCS format EPS files to create a composite PDF file (except for layout in Adobe Indesign).

Printouts on a color inkjet printer can not serve as a sample of the color reproduction of the original

General requirements for layout files

- The size of the document in the layout program should be equal to the trimmed format of the finished product (for files in PDF format this size can be larger by the size of the edges).

- It is not allowed to use files with the same name lying in different folders (sometimes this leads to a substitution for one file).

Colors

- The order should include a list of all colors (number and type) for which color separation will be performed

- When using color separation with the help of color ink (CMYK), it is obligatory that the colors of all the image elements in the graphics file are described in the CMYK color model. It is not allowed to use other models (RGB, HSB, ...). In the layout file, all element colors must be of type process, not spot or tint

- All raster images must be 300 dpi, also executed in the CMYK model only !!!

- When using Pantone colors, all objects of this color should be described in a scale of the same type

Fonts

- In Corel Draw all fonts are converted to curves

- All used fonts must be submitted together with the layout / graphics file

- When sending PostScript fonts, do not forget both font files (.pfm and .pfb on PC; PostScript font).

- When creating a vector EPS file, you should use settings that convert fonts to curves

- Preferably use PostScript fonts, it is undesirable to use unchecked, hand-crafted or edited fonts, as well as system fonts.

- It is not recommended to mix fonts in one layout of TrueType and PostScript.

- When working on PC, make sure that there are no PostScript and TrueType fonts with matching names.

- Make sure that the EPS files imported into the layout / graphics file do not contain any fonts.

Note:

- If the program, in which the layout was made, allows you to convert fonts into curves, then it's better to do so.

- If the program Adobe Indesign used raster effects, the fonts must be converted to curves

Related graphics used in layouts

- All linked graphics files must be submitted together with the main layout / graphics file even if they are fully included in it

- For linked raster graphics files, only three formats are allowed: TIFF (300 dpi), Photoshop EPS, Photoshop DCS 2.

Note:

Use the Photoshop DCS 2.0 format only if you are printing additional colors. Set the options to Preview - TIFF (8 bit / pixel), DCS - Single File with Color Composite (72 pixel / inch), Encoding - Binary /

A warning:

- When using the Photoshop EPS format, the Encoding option must be set to Binary.

- All related raster graphics files must be in color models CMYK, grayscale, or bitmap;

Note:

- When using the Duotone color model, you must clearly understand what exactly you want to get as a result. It is preferable to use the equivalent in CMYK.

- For associated vector graphics files, the EPS format is recommended

- It is inadmissible to place items in the layout through the clipboard area, use the built-in (embeded) files created in other programs, put in the layout of the files in the PSD format. (except for the layout in Adobe Indesign).

- If you want to use illustrations created in specialized programs that do not support the CMYK color model (diagrams, tables), you need to translate them into vector (or raster) EPS (TIFF) format and the corresponding color model. More preferably, the production of diagrams by means of vector graphics programs and direct typing of the table in the layout program

- When using linked raster graphics files with clipping path (clipping path in Adobe Photoshop, container in CorelDRAW !, etc.), you should monitor the number and location of nodes in the contour curve and optimize its shape as much as possible. When processing a file that contains an illustration with a complex shape clipping path, with a large number of nodes, or with closely spaced nodes, there is a high probability of a PostScript error, for the elimination of which, as a rule, a significant alteration of the elements of the source file is required, which entails disruption of the transit time order

- When creating an image with a lot of complicated illustrations, it is advisable (if possible) to use one large-format background image collected by means of Adobe Photoshop, instead of one or several illustrations with a contour superimposed on the background. This greatly speeds up the processing of your file on the RIP, and leads to a decrease in the volume of the source file, and the end result looks more attractive.

- Multiple embedded EPS should be avoided (EPS was loaded into the graphics file, from which another EPS was made, which was loaded into the layout, from which ... etc.);

Note:

- It is inadmissible to embed in the layout files from Adobe Illustrator with linked raster files

- When using linked graphics files obtained from other sources, you should check the contents (color, size, image quality of the vector files and resolution of the raster files) before installing them in the layout.

- Check the accuracy of the size and resolution of bitmap illustrations before downloading.

- It is preferable to load in the layout of a file with exact dimensions on a scale of 100%. It is not advisable to scale it, crop it and rotate it with the layout tool

Note:

- All operations for scaling bitmap files must be done in Adobe Photoshop, in the layout programs it is permissible to change the scale within 15% (from 85 to 115%).

When creating layouts of full-color products, the following should be considered:

1) relatively small objects of black color (the text size is up to 20 pt, lines, etc.) should always be printed on top of the rest of the image; (100% Black - Overprint)

2) large objects of black color (large pin texts, large dice) must be painted with the so-called "compound black" (C: 50-M: 50-Y: 50-B: 100). Otherwise, we get a die or "bald", i.e. gray, or transparent, that is from under it will look through the background.

If the image in your layout is printed "under the edge", you need to bring it beyond the edge of the printed field by 3 mm. If this is not done, even a slight shift of the knife during cutting will lead to the appearance of a white strip along the edge of the sheet. If the layout does not provide for the output of the image beyond the edge, this will have to be done to us, while:

a) there will be distortions associated with disproportionate positioning;

b) important elements of the image can be "cut".

Features of CorelDRAW

The widespread negative attitude of staff of some of the repro-centres to the CorelDRAW program! is based on the fact that this program has a large set of special effects that, when used by inexperienced users in certain combinations and modes, can cause difficulties in subsequent processing by a PostScript interpreter. In addition, not all the tools and utilities of the CorelDRAW package! are optimal from the point of view of prepress. The following are the features that should be considered when preparing a job in CorelDRAW !:

- When painting objects correctly choose the color model. Must be used CMYK and PANTONE Spot Colors. You can not use other models (CMYK255, RGB, HSL, Grayscale, PANTONE Process, TOYO, FOCOLTONE, etc.) - this can lead to very unexpected results. For painting black and white objects, it is recommended to use shades of triad black paint (model CMYK), rather than model Grayscale

- Effects such as a lens, a translucent shade, etc. applied to the imported objects of raster graphics, it is preferable to perform in PhotoShop'e or rasterize them directly in CorelDRAW! Together with the object over which they are located (this also applies to such effects used in Adobe Illustrator).

- It is necessary to edit the shape of complex curves obtained after tracing bitmaps to reduce the number of nodes in them

- When opening and saving files, you should pay attention to messages about the contents of the style palette associated with this file; incorrect answers to proposed queries can cause overwriting of all the styles installed on this computer, then - to overwrite all styles of the file in another computer, etc. This greatly increases the file size and slows down the work with it. It is recommended to view the contents of your Styles styles palette (Ctrl + F5) and if there are a lot of extra styles in it - delete them. The best way is to delete the default style palette (the approximate location is C: \ Corel \ Draw \ Template \ coreldrw.cdt) and restart the program. This automatically creates a new palette with a minimal set of styles. After opening the file through the Styles menu, you must load this minimum load styles and save the file.

Multi-page works

As a rule, the receipt of the order for the withdrawal of multipage works is carried out after agreeing all the parameters. Elements that are mandatory for normal works are added here:

- The general layout of the edition

- Symmetrical layout (for files over 8 pages - mandatory)

- Correctly assembled Collect: all fonts, images

- Lack of system fonts in layout

- The cover for the thermobinder is verified by a separate file, taking into account the spine under the thermobinder

- Elements in the layout for the thermobinder should not be closer than 7 mm from the inner root

- A black and white printout of the layout, correctly assembled and fastened.

Requirements for post-printing elements in the file (stamps: knives, creasing, perforations, selective UV varnish, embossing, convex)

- All stamps (knives, creasing, perforations) are given in vector graphics programs with the attribute of stroke without filling (no Fill, only Stroke), stroke thickness - 2 pt.

- Objects for convex and varnish are set in one size, with triadic objects that will be under them.

Correctness of the preparation of a raster file (mainly for objects with varnish, less often - embossing, convex - only large objects, without thin, small elements):

- Post-printing elements NEVER are scaled in imposition programs.

- In work under the spring, information important elements should not be located closer than 10 mm from the edge of the passage of the spring.

Compliance with these rules leads to an improvement in the quality of finished products, speeding up the delivery of the order
