and support at 10%
Why did it take so many attempts? Because adjustments to the percentage figures of two or three percent gave me bigger jumps in the sizes actually printed. I couldn't get what I wanted. I still don't have precisely what I want but what I have is acceptable.
I have come to the conclusion that ideaMaker only accepts changes in the percentages in 5% increments. I can't for the life of me figure out why that would be but it seems to work. Has anyone else had the same experience?
