Today I went to make test prints and the results look very promising.
The people at Tiggelman repro were very helpful. They suggested I use a paper called Reviva which has a nice newspaper look. The lines I use in my design are only 0.4 pixels thick and the lighter ones were barely visible when I printed them on my printer. But at Tiggelman they’ve got a very good printer which can print those lines and gives very sharp prints in general. This is necessary as lots of lines are very subtle. They will print a test stack of 500 pages and do all the manipulations like drilling and perforating. I’m really looking forward to holding that first stack in my hands.
