Ink Placement

Avoid inking the head of the paper. This causes the feeding marks and paper jams.

• Place your designs on the bottom of the page if possible.
• Do not use 100% color flat in this area.

Color flat area

The risograph can’t print an evenly flat large color area. Avoid them. If you have a big color area, keep the opacity between 80-95% (depending on the size). Like this you will avoid a watercolor effect, wet ink-spots and paper jams.

Inaccuracy

The risograph has limits of accuracy. The overlaps can be adjusted manually in the printing process but there can always be shifts. This should be taken in account in your design process. Especially when you print double-sided, with many colors or details or something that relies on very accurate imposition.

• Fillings should trap lines
• Don’t overprint text or thin lines (or you’ll get a blurry result)

Imperfections

Slight print marks can appear, especially when printing more than two layers or double sided. Track marks from the paper feeding rollers can appear, especially using heavy inking. But these can easily be removed with an eraser.

Fonts

• Do not set type in photoshop.
• Vectorize your font to avoid any problem of pixelation.
• Size should not go under 6 pt.
• Font under 12pt should be set in registration black (100/100/100/100)
• Over 12pt use a 100% black (0/0/0/100)

Lines

Lines should not go under 0,25 pt.
