Printing and quality
By printing with us you are agreeing to the characteristics of risograph printing which always involves a certain degree of imperfection.
- Ink smudging:
Riso ink might smudge a little depending on the drying process, the amount of ink and the absorbance of the paper. Smudge-free risograph prints can only be ensured by topcoating.
- Colour difference:
Riso inks are unique to this technology and do not follow CMYK or Pantone colour scales. Each colour has a rough equivalent in each scale (see our colour chart) but there will be a difference between the equivalent and the Riso colour. Photographic images will differ from those produced by a digital or offset printer. Furthermore, the inks have a degree of transparency, meaning that overlappings will produce a new colour. The paper will also affect the final image.
- Uneven coverage:
Large, flat areas of colour might present variations in coverage and appear grainy.
Because each layer is printed individually, slight misalignments are to be expected, especially when working on both sides of the paper and in projects that require multiple runs in the machine.
- Tire marks:
The rubber wheel that feeds the paper into the machine might leave some faint marks, especially when projects specify heavy ink coverage on previously printed sheets. These can be cleaned with a rubber in most cases.
We will assist you in making sure that your design minimises such imperfections. However, they can not be completely eliminated and are part of the essence and beauty of risograph printing.
