If you answered "yes" to all of these questions, your files are most likely ready to go on production.
File preparation for saddle stitched brochures:
File preparation for perfect bound (perfect sewn bound) brochures:
File preparation for leaflets (folders):
4 page leaflets shall be provided in single page PDF files. Leaflets with more than 4 pages should be provided in flat-size layouts.
File preparation for UV spot varnishing:
File preparation for die-cutting
A PDF format file shall be provided for die-cutting jobs. Dimensions in a die-cut file shall absolutely match the dimensions in product design file.
File preparation for different language versions
If you prepare a design for products in various languages, where only black is changing for variations, files shall be prepared as follows: background (same for all languages) - CMYK without a text which varies; different language texts - separate files, only black.
Alternative: prepare a PDF file with layers, where background would be CMYK and separate layers for each language.
Every print-ready file must contain:
NO BLEED REQUIRED
A bleed is required when a graphical object (image, text or background) spreads till the edge of your page.
In such case, you have to add bleed to the finished (trimming) size of your layout. Width of bleed shall be minimum 3 mm.
NO BLEED REQUIRED
A brochure layout shall include bleed on three sides: top, bottom and outside. Bleed on the inside is not strictly required.
Important! Bleed on layouts of softcover brochure covers, wire-o brochures and other products (flyers, leaflets, etc.) shall be on all four sides.
NO BLEED REQUIRED
Before you export your PDF file please select the "include bleed" option.
We also recommend you to indicate crop marks and trim marks in your design. These should be software-generated and added at the PDF-making stage by ticking the "Crop Marks" option. Crop marks shall be at least 2 mm from trim box limits.
Make sure your design does not contain any low resolution elements.
Recommended resolution range is 300-350 dpi for CMYK and Grayscale images, and 600-2540 dpi for one bit bitmap images.
In any case quality of printed images of less than 150 dpi resolution may be low.
Also we recommend using only CMYK or Grayscale images, as any RGB images will be automatically converted by our software into CMYK elements, while result may be not what you're expecting.
PDF – ensure you embed all fonts when making your PDF.
EPS – ensure you convert all fonts into outlines when making your EPS.
Smaller than 7 point font shall be composed only from one of these colours: 100 % Black, 100 % Cyan, 100 % Magenta, 100 % Yellow or 100 % Pantone.
Lines shall be at least 0.08 mm thick.
Colour of lines of 0.2 mm or less thickness shall be single coloured, moreover lines shall not be rasterized (100 % colours are required).
Make sure spot colours you use are from Pantone library and are intented to be used in printing of your design.
Do not leave any SPOT colours in CMYK designs; automatic colour conversion may give unexpected result. Most convenient way to check SPOT colours is to select separation preview function in the Acrobat Pro software. Do not use different Pantone colour palettes. For example, the same file may not include Pantone 485C and Pantone 485U colours.
Do not use RGB colours or elements within your design. Every RGB element will be automatically converted into CMYK, while result may not be as expected.
Pure black (100% black) graphic objects will automatically be set to overprint in the prepress stage. Therefore black elements on nontransparent backgrounds (Pantone metallic colours, like PMS 871, 877) shall never be pure black or they might become dimmed. Other colours shall be added to the black mix (for example: C50 M40 Y30 K100) to prevent overprinting.
Therefore we recommend supplementing black elements with other colours (except text < 24 pt and lines < 3 pt) (for example: C50 M40 Y30 K100). That is how we would get so called RICH BLACK. This would help us to avoid undesirable black overprints. Also black with other colours will become richer, than K100 alone.
For the Grey background made of Black colour only we recommend using 5-40 % Black.
For the Grey background made of CMYK we recommend using 5-20 % of CMY and 5-100 % of K 5-100 proc.
Grey shall not be composed of CMY only, without Black, while share of Black shall be greater than CMY.
In case you accidentally set the “overprint” function for a filling or a line (which are overlaying other elements in the design), result will differ from the design, as paint is transparent.
In order to check if the design is prepared correctly, activate the "Print Preview" function in Advanced/Print production menu of the "Acrobat Pro" software.
Fountain fills and transparencies
Do not use fountain fills in spot colour jobs as this will cause your job to be rejected by prepress.
Do not use transparency functions of Microsoft and CorelDraw software. Please flatten any transparencies in the Adobe Illustrator or the Indesign prior to generation of PDF.
Never use multi-layer transparencies as this may cause problems when your file is processed through our workflow, and may not give the desired end result.
Total ink limit
Do not apply any colour, which total ink limit exceeds 300% (which is calculated by summing all C, M, Y and K elements together) in your design.
Please note, that our software will automatically decrease total ink limit till recommended for particular type of selected paper. For a coated paper - 330%, for uncoated paper - 300%. In general it will not affect colours, at least you will not notice much difference, however, in order to avoid such conversion, try not to overcome 300% of total ink limit.
We recommend using ISOcoated_v2_eci.icc color conversion profile for regular machine coated gloss, silk and mat papers. This profile allows maximum ink coverage up to 330 %. For high bulk coated papers (like Arctic Volume or similar) we recommend to use ISOcoated_v2_300_eci.icc profile, where maximum ink coverage of 300% is allowed.
PSO_Uncoated_ISO12647_eci.icc conversion profile is recommended for uncoated paper, which limits the total ink coverage to 300%. If for some reason, total ink coverage in your file will be higher than 330% for coated paper and 300% for uncoated paper, additional color management will be applied by our prepress.

Slight colour variance on a printed product is inevitable because of many factors influencing printing process.
This means that colours may slightly differ from original design despite of printing quality, which is compatible with requirements of international standard and allowable tolerances.
On jobs with multi sheet products (especially books and brochures) there may be a variance in colour within the design itself (within limits set by the standard).
Also we would like to note, that subsequent reprints may slightly differ in colour as well.
Image on the screen is composed of RGB colours; therefore it cannot be replicated with ink on paper exactly, where CMYK system is used. Moreover, screen image quality depends a lot on calibration of the screen.
Important! The first page (cover) of a Letter type leaflet shall be wider than other pages. A width of pages of a Z type leaflets shall be equal.
Files for leaflets with more than one folding line, i.e. six page leaflets, eight page leaflets, etc., shall be supplied as a flat-size layout.
Layout size mm
X - inner block width, Y - inner block length, Z - spine width
