- 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.
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 /
- 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;
- 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.);
- 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
- 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".
