This week I saw a stack of Lexmark printers in a small supermarket called Aldi. I don't want a printer even if the fifty pound price tag is a bargain. What caught my eye was the large print on each box 4800X1200 DPI. I guess it means horizontal definition is 4 times higher than vertical, ...both to me pretty high. Not that I disbelieve it, but it can't be easy with wet ink to keep apart the dots? For a time I have been preparing a chart for testing some properties of digital camera optics. A search for lens test chart on google gives pages of info but not what I wanted, so I have sketched out my own. I don't claim it is brilliant. I merely wanted to know if these new zoom lenses were rectilinear,- so you could copy a pcb and retain the hole positions for ic's in the transfer sheet, or snap a framed picture without getting barrel distortion. I also think astigmatism is worth looking for... but I must go back to the thread. It occurred to me that if I could introduce a parameter into a print file for my chart, making it wilham mk2 instead of mk1, it could be a very useful tool, -even to test a Lexmark. When I looked into this I found the software to print mk2 more difficult than expected. If soanso is willing to have a go at it we'll call it the wilham/soanso chart which is cheeky of me because it is some challenge. Please don't send any files directly to me. I hope any o/p after I've given the design details will be freeware, but if it does turn out well maybe we ought to grant PCAdvisor some priority/credit. It's getting late for me, I'll fill in the details tomorrow. Meanwhile can anybody suggest how a program for mk2 could be shown. There was a web site that offered free parking for your dig'l pic up to 30MB mentioned in my last thread re wedding pictures, ...perhaps something like that? More tomorrow. Night!
