MATERIAL INSTRUCTIONS
LARGE FORMATS

When submitting printable PDF materials, please check the following:

1. IMAGE RESOLUTION

Continuous-tone image resolution should follow the limits for 1:1 sized images mentioned below.

  • 72–150 ppi
  • for photo paper, 200 ppi
  • for large fabrics, 50 ppi

For line art, the recommended resolution is 1,200 ppi for all printing methods.

Sufficient image resolution


2. BLEED MARGINS 5 MM

All materials must come with 5 mm bleed margins. Without bleed margins, there may be unwanted white areas on the edges of the printed product.

  • for one-sided prints: 5 mm
  • for two-sided prints: 10 mm
  • note: rollup materials must have a 200 mm installation margin
  • Sewing margins for different post-treatment methods:
    • Clean cut fabrics must have a 5 mm bleed margin.
    • When the edge of the fabric is folded and sewn (hemming), please leave a 20 mm sewing margin for each edge to be sewn.
    • There should also be a 20 mm sewing margin for a reinforcement band.
    • Tunnel hems need a sewing margin three times the diameter of the pipe. E.g. for a 50 mm pipe, leave a 150 mm sewing margin to the material.

Don't forget about bleeds


3. FONTS

  • Fonts must be complete and embedded in the PDF.
  • Fonts included in graphic files are most likely to work when converted into paths.
  • Reverse types (white text on a coloured background) of less than 10 points must be discussed with the printer due to a possible misalignment affecting the readability of the text.

If you’re unsure, please ask


4. LINE THICKNESS

The smallest recommended line thickness is 0.25 pt. Narrow lines should not be used for multi-colour, rasterised or reverse printing.


5. COLOURS

For four-colour works, we recommend that you define the colours as process colours (CMYK), only any additional colours are defined as SPOT/PANTONE colours. For digital printing, you can also use RGB colours in the images: our default profile for RGB images is sRGB. Be sure to always embed RGB and CMYK profiles in PDF files.

Our recommended CMYK colour profiles:

  • coated paper: IsoCoated_v2, Coated FOGRA 39
  • uncoated paper: IsoUncoated, PSO Uncoated

If you are using RGB materials, we recommend that you submit a layout package.

6. CREATING A PDF

Regardless of the printing method, please note the following:

  • Always include cutting lines in the PDF (with a 3 mm margin)
  • The material must be centred on the page
  • The material must be divided into individual pages, no double pages
  • All pages must have the same size and same orientation

Please note that PDF proofing and any additional work due to it will be invoiced work unless otherwise agreed.

 

7. OVERPRINT

Please do not use overprinting for any other partial colour than black or, when using a white additional colour, white. Ask for more information if you’d like to use overprinting for other colours.

8. FOUR-COLOUR BLACK

Please do not use four-colour black (= Registration black of layout programs). As an exception, fabric printing produces the best black with the following mix: C40/M40/Y20/K100.

100% BLACK
0/0/0/100
40/40/20/100

9. SHAPE CUTTING

  • Materials that need to be cut into shape must have cutting lines with the spot colour ”Cut_1” (M100) and overprinting. Ask for further instructions if necessary.
  • The cutting line must be a single continuous line, not several separate pieces.
  • If possible, submit the material with and without the cutting line, making it possible to use the material with as many different printing methods as possible.

10. MATERIAL SUBMISSION

Please submit the material as agreed beforehand. We recommend that you pack the material into one .zip file.

E-mail submission

  • You can submit the material by e-mail. You can find city-specific material submission addresses on the contact page of our website.
