Create Data

Bleed / trim / crop marks

You can find specifics in the data sheets of the product on each site of your desired product.

In which size the data should be created?

You can create the file 1 to 1 in the final format or in a smaller scale (e.g. 1 to 2 or 1 to 10). Please note that the resolution of pixel data must be multiplied by the selected factor, so the quality is sufficient later.
Example:

85 x 200cm         150 DPI         100%        1 to 1
42,5 x 100cm      300 DPI         50%          1 to 2
8,5 x 20cm           1500 DPI      10%           1 to 10

I can not create my data in the final format

You can create the file in a smaller scale (e.g. 1 to 2 or 1 to 10).
Please note that the resolution of pixel data must be multiplied by the selected factor, so the quality is sufficient later.
Some layout programs (e.g. INDD, AI, CDR) can only create PDFs up to a maximum size of 5 m.

Therefore, create your data in a smaller scale.

Data in scale 1 to 10 (e.g. 8,5 x 20 cm)

If you create your data in 1 to 10 (10%), please make sure to increase the resolution according to your scale.
If you create your file in the format 8,5 x 20 cm with 300 dpi, the final format 85 x 200 cm only has 30 dpi and will hence be blurred or pixelated.
Example:
8,5cm x 20cm with 720 – 1500 DPI enlarged to final size: 85 x 200cm with 72 – 150 DPI
30cm x 10cm with 720 – 1500 DPI enlarged to final size: 300 x 100cm with 72 – 150 DPI

Which resolution should the file have?

Offset printers use 300 dpi as file resolution.
Large format prints are depending on the size and may vary between a resolution of 20 and 150 dpi. It depends on the size of the print and the viewing distance since the human eye does not perceive a lower resolution with some distance.
We recommend the following resolution:

RollUps, exhibition displays, banner displays           72 – 150 DPI
Poster starting at DIN A2                                                   72 – 150 DPI
Poster starting at DIN A4                                                   150 – 300 DPI

Banner, textile, sticker                                     1 – 2,5 m²                   72 – 150 DPI
                                                                                   2,5 – 5 m²                     50 – 96 DPI
                                                                                    5 – 10 m²                     40 – 72 DPI
                                                                                  10 – 20 m²                     30 – 50 DPI
                                                                                     ab 20 m²                     20 – 40 DPI

The bigger the print, the greater the viewing distance usually is and thus the resolution of the file can also be lower.

PDF with multiple pages

You also can send us PDFs with multiple pages.
It’s important that you need to inform us if one of the motives should be printed multiple times.

Convert fonts to paths or curves

In addition convert all fonts to paths / curves because we might not have your used font and it will automatically be replaced and printed with another font. Therefore it may come to a altered motive.

Overprint

Do not set an element of your data to overprint. Black doesn’t need to be set to overprint as well.
If elements are set to overprint, they will be transparent or translucent in digital printing or will not be printed at all in the worst case.
Check your PDF, EPS and AI data before printing. We cannot guarantee the correct printing of a file that changed due to overprinting.

Transparencies

Please reduce all transparencies in the PDF output and save the file as a PDF X/3.
Check your PDF file if created by Corel Draw on lines or displacements in the shadows and glows; this often occurs as an error.

Alpha channels / cutting paths

Delete all alpha channels and cutting paths from your TIFF, JPG, Photoshop PDF, PSD and PSB data, since they result in incorrect printing.

Create data for signs with plotter foil

Create the data in the final format or in a scale. Please don't apply crop or trim marks for plotting.
Create your data for the motive as vector graphics, since the plotter will not recognize any other graphics and cannot make any cut. Pixel data such as photos or image gradients do not work.

Line thickness for motives, fonts: minimal 1,5 mm
Font height: minimal 1 cm (with serifs) and 0,8 cm (without serifs)
Fonts have to been converted in paths / curves.
No contours: please only create plains, contours cannot be cut out of the foil

Sticker with cut-path

If you want your sticker manufactured with a contour cut, the file must be created with a cut-path. Please note that the cut-path is only recognized and cut by the plotter if the path show the following characteristics:

- color: 100% Magenta as spot color
- contour: hairline (0,25 PT) 

You can find all necessary information for the cut-path in the data sheet for the products listed below:

Sticker „Standard“
Sticker „Premium“
Sticker „Eco“
Sticker „Car wrapping“
Sticker for illuminated advertising
Wall tattoo

Allowance for hem for banner / flags / textile

Textile materials such as Dekotexx and FlagTex need an addition for sewing the hem.
For special manufactures such as a hemstitch this addition to the final format is necessary.
We recommend to set the background image or the background color in this area.

Exact dimensions can be found in the data sheet of the product on the product page or in your e-mail with the order confirmation.



File formats

Printable file formats

The following file formats can be printed directly:
PDF
JPG
TIFF / PSD
EPS / AI

Please be aware of the information on the individual formats.

What does printable mean?

Printable data are files that can be inserted directly in the RIP and which will be printed directly.

PDF

PDFs should be conform to standard PDF / X-3:2002 and need to show the following characteristics:

- transparency, comments, password protection and form fields are not allowed
- OPI-comments and links are not allowed either
- transfer curves are not allowed
- pictures and fonts have to be embedded completely
- pictures have to be reduced to one layer or rather don't consist of photoshop files with layers

For further information please visit www.pdfx3.org

We cannot assume del credere liability for prints of PDF files due to mistakes that take place while inserting data into the RIP or occur while creating the file. Fonts can be displaced or single elements will not be interpreted correctly under certain circumstances. So please send us an extra JPG as a preview for more certainty.

JPG

save with maximal quality
baseline compression
compression „baseline optimized“ and „progressive“ result in incorrect prints

TIFF / PSD

reduced to one layer
8 bit color depth
no alpha channels and cutting paths
LZW-compression allowed

EPS / AI

fonts converted in paths
images embedded
working area = final format
elements not set to overprint

Please note that AI is an open data format and fonts and images can be replaced. If in doubt export the file as PDF/X3.

Other file formats (e.g. DOC, CDR, PPT, PUB, XLS, ODT, INDD)

Formats from programs such as Corel Draw, MS Word, Publisher, Powerpoint, Excel, Open Office, InDesign are considered as open data, which cannot be printed directly.

Data from InDesign and Corel Draw shall be exported as PDF, JPG, TIFF or EPS.

Please note that Word, Publisher, Powerpoint, Excel and Open Office are not graphic programs and you can only create provisory printable files with them. In that case contact a graphic design agency, a free graphic designer or a friend with graphic skills.



Colors

What kind of color mode should the file be in?

Please create all files in color mode CMYK (8 bit).
CMYK is an abbreviation for the colors Cyan, Magenta, Yellow and Black which are used for printing. RGB (Red, Green and Blue) are colors of light and used for monitors and screens - this color range is bigger and includes brighter colors which cannot be printed.

Color profiles

The following color profiles can be used without problems: Coated Fogra 27, Coated Fogra 39 and ISOcoated v2.
Please note that other embedded profiles may cause color anomalies.

Spot color (e.g. Pantone, RAL und HKS)

Spot colors such as Pantone, RAL, HKS and a real gold and silver aren't printable in digital print. These colors will be converted automatically and rendered to CMYK.

Are there color anomalies in large format printing?

There may be color anomalies in large format printing but in very small amounts so a red won't turn into orange. However, the colors can turn out a bit more dark or light in the end. This occurs due to many different factors, for example the material that will be printed on, if you embedded color profiles and if so, which ones and in which way your monitor is calibrated.

Color anomalies concerning the same motive / picture / color being printed on different material

If you want to print the same motive (i.e. picture or color) on different printing material, for instance pvc-banner and DekoTexx textile, small color anomalies might occur. Since the color affects the different materials in different ways, we recommend a proof on both materials if the colors must be exactly the same.

Also, we recommend to create a file with the size of DIN A3 with the desired color and varieties of it (i.e. 5% more cyan) so you could choose the optimal shades after seeing the proof. The article "Proof" can be found in the category "Accessories".

Optimal values for black

The CMYK value 60 / 40 / 40 / 100 can be recommended for a deep black. Mixing Black with Cyan will achieve a deep and bright Black which is suitable for wide areas. Furthermore, the color appears deeper when compared to 0 / 0 / 0 / 100 Black.

How strong is the ink saturation in large format printing?

The outcome differs from the material that will be printed on.
The following materials posses a good ink saturation: pvc-banner, poster, sticker, backlits.
Textiles have a lower ink saturation for example. Textiles for flags have a poor ink saturation.

Gradients in large format printing

Vector gradients are sometimes slightly streaky in Adobe Illustrator and InDesign. It helps to create the gradients in Photoshop in a 1 to 1 scale.
Some better results can be achieved if you create a .ps-file in InDesign and convert it to a PDF with the help of the program Distiller.
However, a gradient consists generally of single steps for technical reasons (maximum 256). Depending on the length and the selected colors these steps are more or less visible.

Please note that this is due to the file and does not occur in the printing process.

Order a proof

Feel free to order a color proof. The proof will be printed on the original material – e.g. banners, polypropylene, posters, stickers - with the identical print settings in DIN A3 and gives you an idea of ​​how your colors will look like and the final quality of your product.

You can choose between a 1 to 1 detail of your motive or the complete motive scaled to DIN A3.
Please specify your choice in your order. Feel free to send us a separate file for the proof.

If a particular color (e.g. your corporate color) has to be printed, we recommend to proof a color chart.
Create a file with 10 different variations of your desired color (for example in the shape of boxes with the corresponding CMYK values​​). This way you can choose the color that matches your corporate color the most.
For an example, see the following link (PDF).

A proof costs 15, - € net. Each additional proof for this order costs 10, - € net. The article "Proof" can be found in the category "Accessories".

Please note that this will eventually postpone the actual delivery date of your order.

Send a proof to us

Please note that we are not comparing or calibrating the printer according to your proof. They are created by other printers with different materials and colors and will not achieve the same color result as the products, which are printed by us.

But you have the option to order a color proof from us and then adjust your print file.

The proof will be printed on the original material – e.g. banners, polypropylene, posters, stickers - with the identical print settings in DIN A3 and gives you an idea of ​​how your colors will look like and the final quality of your product.
