General informationVariations & tolerances
We produce according to the PSO standard. Even with correct production within the permissible tolerances, noticeable colour variations may occur. The PSO permissible tolerance allows ∆E ≙ 5 per channel. This means that visually a deviation of 5–10 % ink coverage may be noticeable.
Attention! For combination printing, we offer HKS and PANTONE colours only from the current colour charts "HKS Klassik K/N" and "Pantone Solid Coated/Uncoated".
Please use the following colour profiles:
Coated papers: ISOcoated_v2_300_eci.icc
Uncoated papers: PSO_Uncoated_ISO12647_eci.icc
Please note: Our current profiles can found in the download area.
The maximum ink coverage results from the sum of individual colour channels (C+M+Y+K). For example, red: C: 0 % + M: 100 % + Y: 100 % + K: 0 % = 200 %.
|Coated papers:||max. 300 %|
|Uncoated papers:||max. 280 %|
|Per colour channel:||min. 5 %|
Please note: At an ink coverage of less than 5 % (per channel), we can no longer ensure printing. Colours are either no longer perceptible or are not printed.
Special colours (Pantone/HKS)
In combination printing, we offer all HKS and Pantone colours from the current colour charts "HKS Klassik K/N" and "Pantone Solid Coated/Uncoated". If you require colours that are not part of the current special colour charts, we are happy to implement these in individual printing.
We recommend that you do not set special colours to overprinting, since they will otherwise mix with the process colours (CMYK) underneath. In combination printing we cannot influence the order in which the colours are printed.
If special colours are desired, they must be ordered in the shop:
If no special colour was requested, the print file must not contain a special colour. Please convert special colours that weren’t ordered into process colours (CMYK).
Of course, special colours that are created for finishing or further processing must be included in the file.
Use of neon colours:
When using neon colours from the Pantone or HKS system, please note that, for example, a combination with UV coating will significantly reduce the luminance of the colour. In order to obtain the optimum colour intensity, you should also not mix neon colours with other colours by overprinting, but always set to cut out in the file.
Both black (5-100 % K) as well as coloured elements can only be printed cleanly on gold and silver if they are not set to "overprinting". Otherwise the metallic effect will be lost or CMYK elements will lose colour intensity and become indistinct and poorly discernible.
Metallic colours in combination with:
|UV coating:||Changes the effect, metallic effect is lost|
|CMYK objects:||Always set to knockout|
|Black text < 8 pt:||Is automatically overprinted; if this is not desired, please convert the font to paths and set them to knockout (100 % black [K])|
Please note: In combination printing, we cannot influence the order in which the colours are printed.
The registration colour named "All" is for print marks. It consists of 100 % each of the colour separations cyan, magenta, yellow and black plus the special colours used. Due to the excessive ink coverage, the registration colour must not be used within the layout.
Vector objects with registration color
Vector objects are always converted to 100 % K. If additional image objects with registration color are on the same page, there will be visible differences in the black display of these objects (see "Image objects with registration color").
Image objects with registration color
Image objects with registration colour are reduced in colour application to our prescribed standard (300 or 320 % colour application). If there are also vector objects with registration color on the same page, there will be visible differences in the black display of these objects (see "Vector objects with registration color").
Overprinting CMYK white
White text and design elements (C: 0 % M: 0 % Y: 0 % K: 0 %) that have been assigned the "overprint" attribute are not visible after printing and must therefore always be set to knockout.
Note: To maintain the visibility of white front and objects, you must always set to knockout. Elements to which white or paper is assigned as a color are usually automatically omitted. However, if objects with other colours are subsequently used with 0 % ink coverage or if the elements themselves are assigned the attribute "overprint", they are no longer visible after printing. You can check this with the overprint preview of the layout program or Adobe Acrobat.
Substrates with a transparent background can be underprinted in white (e.g. transparent stickers). For silver-metallic paper, opaque white can be ordered as an additional option.
Elements that are to be underprinted in white must be duplicated and set up with the overprinting special colour named weiss and with the following parameters:
|Set up as:||Vectors or pixels|
|Colour for visualization:||100 % cyan|
|Colour type:||Full-tone colour/special colour/spot colour|
|Overprinting:||Overprint surface and/or contour|
Attention! Please do not try to simulate the overprinting behaviour of special colours through transparency effects (multiply, overlay etc.).
When processing the print data, the opaque white is automatically set to overprinting! If there are supposed to be objects underneath the opaque white areas, they must additionally be created underneath the opaque white and should also be correspondingly coloured.
In case of e.g. white objects on a coloured background, the opaque white must not be set to knockout. An object in CMYK white (C: 0 % M: 0 % Y: 0% K: 0%) must in fact be created underneath the opaque white.
