Simulated process separations were our choice for this T-shirt design, the subtle tones required for the egg were not suited to the index process. We find simulated process separations are a little more time consuming to create but they really can produce the highest quality prints.

We used 61T and 77T meshes for this print, 77T is not an ideal mesh for waterbased ink it held the half tone with no problem at all, but they required flood bar and squeegee tweaks on the machine to print well.

On the other hand 61T mesh printed with no problems at all, but the halftone on the blue screen suffered from moire patterning. This is possibly due to the mesh on the Newman frame being slightly off true square, as the yellow, also on a 61T mesh, was fine. Or was the yellow screen stretched off square? It is difficult to know for sure so a lot more care will be taken when stretching our Newman Frames in the future. With only slight moire on one screen we decided to go with it, there is no pattern visible on the final print, see rear side of duck above. The ideal screen angle for the 61T is what we are concentrating on now.
