Preface: I'm a newbie!
I have been lucky enough to sometimes print jobs that had little to no problems. Other times (such as now!), I have issues I simply seem unable to fix. :[
Here's the problem:
In the design of a card, I have text that is 9 points tall (Gotham)...Blobs appear within the small circles of B, 9, and so forth, while other, larger text appears fine.
See images for examples of what I have tried and the best that it's done. You can see that even with less packing and the chase adjusted outward, the blobs still appear.
Things I've tried:
- Checking roller height with the lollipop and adjusting as necessary.
- Removing or adding packing.
- Cleaning off my plate in hopes it was just dried ink.
- Running at least 10 prints to see if it would get better.
- Adjusting chase outward (meaning, less of impression) - the C&P has two knobs to do this.
- Chandler & Price 10x15 Craftsman (1965; it is an automatic model, but I hand-feed it)
- Boxcar Base (Deep relief)
- Polymer Plate KF152
- Very new rollers (re-done by Advanced Roller Co. in CA)
I have strong suspicions my text was just too small. Gotham 9pt, measures at 2 millimeters as printed. I am really hoping the answer is not to get the plate re-made with bigger text. :(
Packing thinned, chase adjusted for less of impression: you still see blobs.
Intermediate next steps back toward more packing and chase brought in a little more: still blobs --
Another step up:
The best I could get it
To me it looks like it could be too much ink, too little pressure or packing, and naturally bumpy stock. Maybe try taking about a third of the ink off the disk, adding a sheet of soft packing, and see if that helps?
