CMYK Angles Screen Printing an Overview Posted On: Aug-18-2020 By: Alex Jones

CMYK angles screen printing is advancement in the screen printing industry that has allowed printers to go beyond the four colors and to expand the color variety for printed images. Following the color printing theory, the screen printing industry is looking for ways to innovate methods of screen printing, and consideration of CMYK angles is the perfect example of it. 

What is Screen Angle?

In the course of color prepress and printing, the angle at which the rows of halftone dots run in relation to the horizontal is called a screen angle. To eliminate unwanted moiré patterns at the time when four-color split-up halftones are overprinted in screen printing, every screen requires to be positioned at a diverse angle, as the marks of one color interfering with those of others, generating the dissimilar moiré patterns. To minimize moiré patterns in the printing outcomes, printing experts suggest that all the screens must be at 30º from each other.

Standard Screen Angle Sets

The following screen angle sets are found useful and are in regular use for CMYK angles screen printing. The sequence for the screen sets listed below is Cyan, Magenta, and Yellow, K (the most visible color/Black). 

Standard 4/C European Screen Angle Set

15, 45, 0, and 75 (Here is the possibility of moiré in greens as C and Y are just 15º apart)

Standard 4/C U.S. Screen Angle Set

15, 75, 0, 45 (probable moiré in greens as C and Y are just 15º apart)

Other Working Screen Angle Sets

Bear in mind that whenever two colors are less than 30º far, there is a possibility of moiré.

C  15°  15°  15°  45°  45°  75°  75°  75°
M 75°  45°   45° 15° 75° 15° 45° 15°
Y 30° 60°
K 45° 75° 45° 75° 15° 45°  15° 45°


Screen Angles for Different Screen Printing Jobs
 
For 2/C jobs

Other angles are also usable; however, the supervisory principle is that the positions should be 30º or 45º apart, and the darkest color should be at 45º to decrease its perceptibility and lower sawtooth.

  • The dark color at 45°
  • The light color at 75°

For 3/C Jobs

  • The darkest color at 45°
  • The medium color at 75°
  • The lightest color at 15°

Coping With The Yellow Printer Moiré Problem

Inter screen moiré turns out to be more observable when the angles of any two films are lesser than 30 degrees apart. Yellow is generally allowed to be lesser than 30 degrees, as it is a bright color that the moiré is normally not visible. Also, the occurrence of the yellow imprinter is typically made higher than the other three colors, 108%, to further minimalize the perceptibility of the moiré. But the moiré can turn out to be more noticeable if the yellow printer turns into dirty/stained by the continuing processing colors, or if its concentration is too high.
