1. Overexposure during exposing. Change
Time!
2. Artwork not opaque enough. Darken It!
Oil from skin left on screen. Remove photo emulsion, wash the screen thoroughly and start again!
1. Too little sensitizer. Measure Again!
2. Short exposure time. Change time!
3. Improper distance. Change Distance!
4. Water too warm or pressure too strong.
Use cooler water or change pressure!
Emulsion too thickly applied. Apply less!
Emulsion too sparsely applied. Apply more!
When water-based ink dries in screen – use spray bottle with water and spray directly on the screen. Just a small amount will open it up. Certain inks will not wash out if they dry in the screen, so be careful not to leave the screen inked without printing, or the screen may be ruined. CrownTM Retarder works well to slow down drying time and keep screen open longer while printing.
Spray inside of screen only. If the outside gets smeared you must wash the entire outside or print until the smear disappears.
Oil based inks are more flexible in terms of drying time. Use ink thinner or screen wash on a paper towel and apply directly to inside of the screen where the ink has dried. Do not rub the outside of the screen. If the outside is smeared you must clean the entire outside or keep printing until the smear disappears.
Always test print before production runs.
If you have problems that you cannot solve and your local dealer cannot help you, do not hesitate to call our factory.
