| Sizes | | Final Trim Size | | Any size of the finished piece (including irregular shapes) not larger than 680 x 480 mm. | | Full Bleed Size | The artwork must consist of the final trim size of a label extended by the bleed, the artwork of the white underprint (only for transparent foil) and separately the trim lines (for cutting).
Thanks to the special use of foil, depending on the expected effect you can design differently and freely colour prints, white underprints and trim lines. However, you should remember that the print cannot exceed the print area of 682 x 482 mm and trim lines should not exceed 680 x 480 mm. Moreover, white underprint should not go beyond printed graphics.
The projects viewed under the surface should be prepared in the mirror (mirror-image) what will prevent possible confusion while ordering. | | Bleed | In case that the designed graphic elements/background are supposed to be printed up to the edges, they must be extended to the bleed area that goes beyond the trim/cut line. The size of bleed should be 2 mm at each side.
In case of shapes other than rectangular, do not extend the background to the whole area beyond the trim line – only to the 2 mm bleed. The rest of the area beyond the finished piece should remain unprinted. | | Single Label | - labels can take on any shape
- Important elements should be placed at least 3 mm from the designed trim line.
- Do not design frames, borders, etc. near the cut line (leave at least 5 mm). It is essential to allow some leeway for trim movement, otherwise printed pieces may not look aesthetically pleasing.
| | Trim and crop marks |
- Trim marks should be designed as hairlines in 100% black.
- The distance between trim marks should be at least 3-4 mm.
- Considering the duration of trimming, while designing:
- You should use straight lines instead of curved lines wherever possible.
- You should use as few vertices as necessary for the delineation of the curve.
- Trim marks cannot overlap.
- Trim marks of a single label should consist of a single closed curve.
- When designing trim marks, avoid placing the beginning or the end of the trim marks on a curve (both should be in the middle of a straight line preferably).
- When aligned with the artwork, trim marks should be saved in a separate file or on a separate page of the same file.
Please note! Trim lines should consist of a minimum number of vertices necessary for the creation of a required shape and ungrounded increase in curve vertices results in slowing down the plotter operation.
If it turns out that the curve complexity causes excessively slow plotter operation, the job will be stopped due to an incorrectly prepared file. |

| 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. | | Rich Black | To achieve a full, dark black, use a black color composed of 33%C 33%M 33%Y 100%K. For printing on backlit materials, use 60%C 55%M 50%Y 100%K.  | | Tone Gradation | Do not set your tonal range for values smaller than 5%.
| | Optimum Resolution | | Optimum resolution for bitmaps (graphics, photos) is 600dpi.
| | Layout | Turn the artwork by 90 degrees to check if bitmaps rotate correctly.
Set all texts on a separate top layer.
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.
Given the base positioning tolerance, there may be some shift in the job relative to the utility. Therefore, we discourage placing any kind of frames around the project, whose non-centricity on the utility can be seen.
All pages in the file should have been done in the same print orientation.
By default utilities are reversed "Head to Head". |
PLEASE NOTE!
Printing on colour media, except for white materials and milky plexiglass, requires white underprint.
White underprint design must be prepared as a separate piece of artwork.
Printing on transparent plexiglass is done on the reverse (as a mirror image) with white colour applied subsequently. The mirror image artwork must be provided by the client.
For one job, prepare just one cutting grid for curved-line trimming. |
White Colour | UV plotter offers the possibility of white colour printing. This means that white colour only or CMYK colours with white underprint can be printed on colour and transparent materials.
To order products with white underprint, please prepare artwork containing 3 {dodstr} pages:
- the first page with colour artwork,
- the second page with white underprint (on colour and clear materials only),
- the third page with the shape for curved line trimming (only when this option is selected).
You can also prepare separate files – one with the colour artwork (with the word ”colour” added to the file name), the second with the underprint (the file with white underprint must have the word „white” in its name), and an optional third file with the shape to be cut out (with the word ”cut” in the name).
After doing this, compress the files together as ZIP or 7z.
For example:
personalised transparent cards, 60 colour cards with common underprint – file names:
cards_transparent_colour.pdf (60 color pages), cards_white_60x.pdf (1 black and white page).
Preparing a file with underprint
Copy your artwork to a separate file and change all colours to black (100% K). The change from black to white is done automatically by the printer software.
For small texts in black colour (100% black) the ground print isn't required.
PLEASE NOTE!
White objects defined as C0%,M0%,Y0%,K0% will be transparent in the printout. |

| Preparation for personalisation | | Final Trim Size | For personalised print, you need to prepare an additional database. Instructions for preparing this are available in a different section:

| Saving to File | | File Formats | Preferred: PDF
Accepted: (unrecommended) CDR, TIFF i JPG (in other resolution than 600/300 dpi).
| | Additional Information | 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)If Curved Line Trimming has been selected, the artwork containing the shape to be cut out should be saved in a separate file (using the word 'ciecie' [which translates to 'cutting' in English] in the name.
You can add preview to your artwork (you must write 'preview' in the name of the file).
For artwork with an underprint, please see the Graphics section (above) on how to prepare files.
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. |
