- always use the shortest file name, max. 31 symbols.
- use only a-z letters or 0-9 numbers in the names.
- use an underscore (_) instead of a space. The use of other special symbols is not allowed..
- use dot (.) only before file identifier.
- label ads according to logic: journal_advertisement.
- example of successful label: magazine №8_p17.pdf.
- Adobe PhotoShop (*.pdf,*.psd,*.tiff);
- Adobe Illustrator (*.pdf,*.ai,*.eps);
- Adobe InDesign(*.pdf,*.indd).
Using format *.jpeg for raster images, it should be remembered that the compression ratio is achieved due to the loss of image quality; application of formats *.gif, *.bmp, *.pict, as well as images placed in layout through «exchange buffer» is simply forbidden.
- we accept layouts prepared in layout programs InDesign CS-CS6.
- together with the layout, it is necessary to provide all the fonts used and their styles (put in a separate directory, do not provide extra fonts).
- all imported images should be placed in one directory, do not embed them in the document, keep in touch. For objects in links, avoid the same file names. It is best to do this through the special function Package (pack) in InDesign.
- vector images are accepted prepared in Adobe Illustrator CS-CS6, in some cases in CorelDraw 9.0-Х6.
- all applicable fonts should be converted to curves.
- bit (raster) images in the program Adobe Illustrator in the illustration do not include, keep in touch (links). In CorelDraw, bitmaps must be embedded in the document.
- if you place Adobe Photoshop files (PSD files) in CorelDraw documents and apply special effects of the CorelDraw program (lenses, shadows, transparency, glow, special fills), they must be rasterized, otherwise the printing house is not responsible for their incorrect conversions. When using the effects of shadow, transparency, glow, etc. in Adobe Illustrator you need to apply to them an operation Object/Expand Appearance.
- bit (raster) images are accepted in TIFF, EPS (encoding ASCII, Binary) formats with a resolution of 225-350 dpi (in real size) in the CMYK color model without additional channels (alpha-channels).
- all used layers should be combined into one layer (command Layer/Flatten Image).
- when using raster objects with a resolution of more than 350 dpi, the resolution is automatically reduced to 350 dpi, as a result of this conversion, image quality can be reduced (sharpening, color tone shift, etc.). Therefore, in this case, the printing house does not accept complaints about the quality of raster images.
- the size of the product must be agreed with the specialist of the printing house, since the selected format of the future publication may not correspond to the technological parameters of the printing and post-printing equipment;
- for all types of works should be prepared «edges» (allowances) of 2 mm. The location of significant elements from the trim format must be at least 3 mm;
- «TrimBox», if there is information about yourself in the files, it must correspond to the cropped format and describe it.
- For products on the spring (notebooks and catalogs), provide a cut allowance for the cover of at least 3 mm.
- lines with a thickness of less than 0.5 pt (0.17 mm) are not allowed. We do not recommend using thin lines in raster or multicolor images.
- when using thin lines, it is necessary to consider the minimum thickness reproduced during printing, depending on the density of the raster:
In case of non-compliance with the requirements, the probability of loss of thin-line elements during their reproduction is high.
Depending on the color of the text, the minimum font size should be equal:
- for chopped sets - 6 pt (CMYK), 4 pt (monochrome color);
- for clipped sets - 7 pt (CMYK), 5 pt (monochrome color);
- inversion for chopped sets - 7 pt (CMYK), 5 pt (monochrome color);
- inversion for clipped sets - 8 pt (CMYK), 6 pt (monochrome color).
t is not always possible to track the presence of elements that do not correspond to the above parameters, especially at the stage of prepress preparation of layouts. Often this error appears only when printing a print run. A correction of such «bugs», identified in the adjustment, entails unavoidable costs for the repeated withdrawal of forms and adjustment of equipment, and may also cause a change in the timing of delivery of finished products.
- in the layout use only the CMYK color model and / or custom (spot) colors (in this case, you must provide the exact name of the specified colors) or Grayscale.
- by default, all overprints are removed, if special use of the overprint function is necessary, it is necessary to notify the person accepting the order about this. By default, all work is set to the overlay attribute on solid black paint (overprint Black 100%). Responsibility for execution of Overprint modes is put entirely with Customer!!!
- fill large backgrounds eith «deep black» (for example, CMYK 60/40/40/100).
- it is not permissible to use a black die with the composition: CMYK 100/100/100/100. If such a composition is present in the layout, it is converted to 100% Black by default. Depending on the nature of the image, and in connection with technological necessity, the printing house, at its discretion, can apply trapping with the necessary parameters.
- The layout should not contain any ICC profiles. In the presence of color profiles, the raster processor automatically deletes them, which does not always lead to the desired result.
The presence of gray elements prepared from 2, 3 or 4 colors is not recommended. « Spot colors » need to be prepared with the smallest CMYK components to ensure more accurate color reproduction. Gray color needs to be received only from black color (Black). Otherwise possible «multi-tone» in the circulation. The total brightness of the images should not exceed 320%. Otherwise, effects may occur, such as«offset» (shadowing), unworked elements in the shadows and « plucking out» of paper fibers when printing. The layout should not contain any ICC profiles. In the presence of color profiles, the raster processor automatically applies them, which does not always lead to the desired result. Printing equipment of printing house «Ukraine» is configured according to standard ISO 12647-2:2007.
To control the quality of color separation and as a color standard for the printer, only color proof can be used. Prints from a printer or digital machine cannot serve as a standard of color! Color proofing should be made on equipment calibrated in accordance with the printing process and with the same procedure for applying inks: (BlacK, Cyan, Magenta, Yellow).
When comparing prints with color proof, the following factors should be considered:
- Color proofing does not take into account the effect of paper on the print;
- Not all shades of the digital sample are identical to the print;
- Shades of color on an analogue proof are always richer than on prints;
- Color-spot, are not reflected in the proof, they can be conveyed by the close composition of CMYK, but it must be remembered that many Panton colors cannot be repeated in CMYK;
- Color proofing cannot exactly simulate the printing process.
- provide all the layouts in curves. If, for some reason, the layout is provided in fonts, it is preferable to use the PostScript font library. Provide them along with your material. We do not archive fonts in our system, but delete them after finishing work.
- it is not allowed to use a font smaller than 6 pt (2.1 mm) when printed with their inversion on a background representing a composite color and / or also when assigning them a shade consisting of two or more colors
- TrueType fonts are not recommended. Their playback on output devices does not give a 100% guarantee.
- do not use the so-called system fonts. In various operating systems, they are slightly different from each other and can lead to incorrect word breaks (when transferred in the form of documents).
- the page format should exactly match the cropped format of the finished printed product.
- в 2 mm cuts should be added to the layout (5 mm for die cutting).
- avoid cropping significant objects. Cropping of these objects can be avoided by placing them (e.g. logos) at a distance of at least 5 mm from the cropping line. For products with glue binding, it is necessary to take into account the effect of the spine on texts passing through the spread. Typically, a tolerance of 13 mm from the inner edge of the page to significant layout objects is sufficient. In addition, glued products must take into account the effect of lateral gluing on the inner covers, the first and last pages. Side gluing reduces the useful page area by about 6 mm from the side of the spine.
- electronic cover layouts for publications fastened by adhesive seamless and thread-sewing methods are provided in the form of spreads taking into account the size of the spine. The thickness of the spine for a particular publication is calculated based on the number of notebooks and the density of paper used. The size of the spine is specified by the printing manager. The back cover spine should be white and have an additional 3 mm on each side for a more durable connection of the block with the cover. When assembling products fastened to a spring, it is necessary to take into account the distance from the edge of the sheet (in the cropped format) to the inner edge of the holes for the spring. Recommended distance of at least 10 mm.
- mark the area of application of varnish / stamping / hot stamping and provide to the printing house in the file of the main layout.
-varnished planes must necessarily be highlighted with additional paint (spot color), with the assigned overprint function (overprint). Do not remove the area of application of varnish on creasing and cutting lines of the product (0.5 mm edge).
- the minimum size of the varnished area is 0.5 mm. The minimum distance between the varnishing elements is 1 mm. The minimum size of the stamping elements is 0.15 mm. The minimum distance between the stamping elements is 0.25 mm. When making clichés for stamping, it is necessary to coordinate with the manager or technologist the possibility of obtaining the desired result on the intended material.
- mark the contour of die cutting in red, creasing in green, perforation in yellow, and provide in separate layers of the main layout file.
- paint the contour of the die in spot color, with the assigned overlay function (overprint stroke).
In the materials to be transferred for subsequent lamination, take into account the edge of 25 mm image around the perimeter of the product in a spread on those. needs
The minimum distance between double numbering is 25 mm. Possible numbering example:
To transfer files, we recommend using the closed file format (PDF format). For sending finished material to the printing house, the closed form of its recording is the most reliable and, in terms of quality, the best. If you use an open form of recording, make sure that all material accompanying the file follows it: fonts, images, logos and graphics. This will simplify processing and save time. To preserve file integrity and prevent information loss during transmission over the Internet, the transmitted files must be archived in ZIP or RAR. If this requirement is not met, and in case of occurrence of problems with the layout due to data loss during transmission via the Internet, the printing house is not responsible.
- on external electronic media by personal delivery
- through file hosting repository;
by emailing of the manager.
In order to prevent loss of information when transferring layouts via the Internet, files must be archived in ZIP or RAR.
If these requirements are not met, the printing house is not responsible.
PRINTING HOUSE DOES NOT CHECK:
- thickness of contour lines and their attributes,
-  color of each object and minimum font size.
- bugs, not finished raster objects, thin.
The customer’s designer must check the finished PDF file before submitting it to the printer. Control can be done, for example, by opening a PDF in Acrobat Reader and printing the material on paper (PS printer). If the printout is correct, and the layout is created in accordance with those. requirements, you can be sure that it will be correctly displayed in the printing house.
