| Sizes | | Final Trim Size | C4 envelope utility size is :229x324 mm
| | Full Bleed Size | | The project must have dimensions identical to the format of the envelope utility designed (See the picture).
| | Bleed | | Do not design background or graphics adjacent to utility edge. The design must not include any bleeds and graphics should be moved away from the edge by 2mm on each side and about 10mm from the top edge of the envelope. (See the picture).
| | Template | In order to make the designing of your business cards easier we suggest downloading a template to prepare your job with.

| C4 envelope template |
  | PLEASE NOTE!
On the template, areas are marked where the envelope is thicker (bends and splicing). When designing uniform colour backgrounds in these areas, be aware that colours can have a different shade than on the rest of the envelope. These differences are especially evident within the boundaries of areas selected in the template. The template serves only as a pattern for designing your own business card. Before saving your artwork please remove the template. Otherwise they will be printed together! |

| Graphics | | Colour Model | Prepare your artwork in CMYK model (except for artwork with additional colour). If your artwork contains halftone images (textures, photos), convert it also to CMYK.
Using different colour spaces or colour models in one document (e.g. CMYK and RGB) leads to incorrect colour rendering and is not covered by warranty.
When defining your own CMYK colours, the total tonal value at one point should not exceed 300% (for one-side coated cards, 200% should not be exceeded on the uncoated side, and, in particular, placing saturated solids in the same place on the face and back of the printed piece should be avoided). If this parameter is exceeded, no warranty claims shall be accepted. (The above mentioned rule means, for example, that black cannot consist of four 100% components.)
For printed materials to be laminated, the total tonal value at one point should not exceed 250%.
Using ICC ISO Coated v.2_300 profile is recommended, whenever possible, as it limits color components to 300%, unlike ISO Coated v.2 profile, which allows components to achieve up to 330%. | | Rich Black | | To achieve solid, saturated black, use black composed of the following components: 60%C 55%M 50%Y 100%K. For digital print, use the following components: 33%C 33%M 33%Y 100%K. | | Gray Large Solid | Offset printing: Grey solid should be created using all CMYK components. Values: C:50% M:40% Y:40% K:22%
Digital printing: If you want the background to be grey, compose it of the 'K' component only, without using the remaining 'CMY' colours. | | Tone Gradation | To avoid visual bands, add some noise to your gradation.  | | Optimum Resolution | | Optimum resolution for bitmaps (graphics, photos) is 300dpi.
| | Layout | Please set texts and any important information (graphics, photos, text) at least 3mm from the edge of a page (in actual trim size) and from scores for folding.
When rotating your artwork by -90 degrees please check whether the bitmaps rotate correctly.
In case of saving your artwork as CDR file, please group all the objects and convert all fonts to curves / paths.
In your file please define your artwork size in accordance with above mentioned size and place your artwork centrally on a page.
If you save as EPS file the artwork which has no background (white), please frame it to above mentioned size.
Due to cutting tolerance some slight movements in relation to artwork edges may occur. For that reason we recommend to avoid those kinds of framing where such distortions could be visible.
By default utilities are reversed "Head to Head" |

| Saving to File | | File Formats | Preferred: PDF
Accepted: CDR, TIFF, JPG (not recommended).
Please note: In case of INDESIGN software, we accept only PostScript files. Otherwise, please use the Comment section to inform us: "Attention: InDesign file. Convert to PS, please". PDF, EPS, PRN
Accepted: CDR, TIFF, JPG (unrecommended).
We are adding the extra fee 3,5 pln, for the preparation of the pdf file to orders with jpg files.
Please note: In case of INDESIGN software, we accept only PostScript files. Otherwise, please use the Comment section to inform us: „Attention: InDesign file. Convert to PS, please"
| | Additional Information | When saving to a PDF file, set the graphics to high resolution. Save your PDF files as PDF/X, PDF/X-1a or PDF 1.3 (Acrobat 4.0.)
If you have text in your artwork please remember to convert it to curves / paths or attach used fonts to your file (refers only to PDF files).
Don't convert texts to bitmaps!!!
If your artwork consists of more than one page, please save all pages in a single file. If the chosen file format does not allow for saving all pages in one file, please save them in two separate files named face and reverse. (projekt_awers.tiff, projekt_rewers.tiff)
In case of preparing separate files for finishing, please include in their name information, which sides concern.
If you send more than one file, please send them in ZIP format if possible.
In case of TIFF files please save them as single layer files, with no additional channels. For complex projects with multiple layers, overlapping graphics, shadows, transparencies etc., as far as possible, flatten to a single background image, retaining texts, logos, lines and other important elements of the project in the vector form only. In particular, this problem concerns CorelDRAW X4, where in extreme cases, despite a good-looking PDF file, the printout may contains errors. |
|
| Additional Information | | | Please keep in mind that due to differences in printing technology and colour presentation, some differences in colours may occur also when compared to inkjet printouts or colours displayed on a computer screen. |
