    Recomended Angles for Flexography.

    Hello friends, first of all thanks for the good advice that is in this forum, I have a question I hope you can help me.

    What are the best angles for CMYK flexo points? or which ones you have used and has given good results?

    Thanks in advance.

    Hi there,

    not easy to answer as there are many good solutions for high-quality-flexoprints.

    In general there should be a difference of 30° between Cyan, Magenta and Black. Yellow must be 15° different to Cyan or Black. No screen-angle should have the same angle like the anilox roller.

    For example:
    K 82,5°
    M 52,5°
    C 22,5°
    Y 7,5°

    Best regards

    1. The angles are depends on the anilox'es angles:
    a) "oldstyle" anilox i.e square cells with 45° - so, "ofset" angles ± 7.5° ;
    b) "newstyle" anilox i.e. hexagonal cells with 60° - so, "ofset" angles

    angles used

    I have a client that prints using the following angles

    C: 82
    M: 22
    Y: 7
    K: 52

    and all spot colours: 52 [unless overlapping screens, then switch them up]

    Recommended angles

    From experience these are the angles I recommend for high graphic work.

    Digital/CTP Plates:
    C= 22.5
    M= 172.5
    Y= 67.5
    K= 52.5

    Conventional/Negatives:
    C= 7.5
    M= 37.5
    Y= 82.5
    K= 67.5

    I have tested a few variations and found the above to be superior in performance.

    Remember the anilox cell angle being 60 degrees.
    This is the reason we offset the entire set by 7.5 degrees.

    There will always be one imperfect angle due to one angle being very close to the 60degree of the anilox.
    This angle will always print stronger/darker. This is the angle which is closest to the anilox cell angle.

    You will find on the digital screenset, I have set the lightest angle which is the Y=67.5 degrees (Close to anilox angle).
    If the yellow ink/separation does print strong it is easily adjusted by altering the ink. or on press adjustments.

    It is forgivable on a light colour as it will not be prominent to a client.
    A person with technical knowledge might pick this which I feel that the chances are remote of picking this up.

    I hope this helps
