Print data

Why do I have to create the data in CMYK and not RGB?
What is the difference between RGB and CMYK?

RGB colors are primary colors in additive color mixing. Additive colors are mixed with light and are used, for example, in television monitors or digital cameras. If you mix all the RGB colors together, you get a white. That is why the color mixture is called "additive". You add colors. For printing, however, the data should be set up in CMYK, as it is well known that light cannot be mixed physically.

The CMYK color space is a subtractive color mixture. In contrast to the RGB color space, all colors are subtracted here in order to obtain white. Cyan, magenta, yellow and black are the primary colors of the subtractive color mixture. A printing plate is created for each of these four colors.

With the so-called RIP (Raster Image Processing) at the latest, all RGB images are converted into CMYK before the printing plates are exposed. This leads to a problem because the RGB color space comprises a larger number of representable colors than the CMYK color space. If images are not created in CMYK, there may be color shifts and color falsifications.
Therefore, if possible, create the data in advance in CMYK mode.

What file format should my print file be?
For printing, you should always save your data in a closed format that can no longer be edited. Resolution, color space and compression play a major role in ensuring perfect print results.

The PDF format is ideal for printing. All extras such as cut contours, hot foil stamping or special colors can be covered here.

For simpler products such as flyers, the file formats JPEG / JPG, TIFF / TIF or, if necessary, EPS are possible.

Please be careful not to send any of the following proprietary data formats: AI, INDD, IDML or PSD.

What resolution should my print file have?

You should create your print file with at least 300 dpi right from the start. The resolution is only important for photos. If your print file is created from a layout program, graphics or fonts are not made up of pixels, but of vectors. You can enlarge a vector file as you like without any loss of quality. However, if you use an image editing program such as Photoshop to create your layout, the print file will always be made up of pixels. In this case, a resolution of at least 300 dpi makes sense.

In the case of particularly large formats - for example banners or larger posters - we nevertheless recommend using a lower resolution of 150 dpi, for example. Since such large print products are usually not viewed from close up, but from a certain distance, the reduced resolution when viewed is of no consequence.

Where can I upload the print data?
You can upload your finished print data to our print data server directly during the order or later in your customer area, please confirm the upload afterwards so that the data is also transferred to us.

If you do not yet have a print-ready graphic, our graphic office will be happy to do this for you. You can of course cancel the order process at any time. If you have already placed an order, you can cancel it; at least as long as your data is not yet in print.

What is the trim and safety margin required for?
A bleed margin is an extra margin that is added to the print file. This is cut off during printing, as there can be deviations of up to one millimeter when cutting to the final format. The trimming therefore provides leeway for these possible cutting differences, since the printing machines cannot print right into the edge of the sheet.

It is important here that the image / color falling off the edge runs into the trimmed edge. So the picture has to be big enough that a few millimeters can be cut off afterwards.

Because of the cutting tolerances mentioned above, we recommend adding a safety margin of 3 mm to the bleed in order to avoid cutting tolerances cutting into important images and texts. Objects falling off the edge are of course excluded here, as these should be cut.

Page orientation

On the basis of the data sheet, which is stored for each product,
you can see the correct side stand. If you have your data
align differently, this will result in incorrect page alignment of the
Printed product.

We handle your data. This means that we can offer your in portrait format
Fold data on the long side, and your data will be in landscape orientation
turn over on the short side.

If you create your data in landscape format, but order a product in portrait format (or the other way around), the rule applies that you enter the data either head to head or
