Basically, I need to create an image with at least 400 dpi which is 181 mm by 55 mm in size.
When I do File > New and specify these dimensions, the canvas size created by Paint Shop Pro is FAR larger than 181 mm by 55 mm. When I do View > Normal Viewing (1:1) it is about five screen lengths wide!
When I reduce the number of pixels per centimetre/inch in File > New, the canvas size is correct.
Surely the resolution should not affect the canvas size of the image?
Anyway, the printers say I must have at least 400 dpi for the image as it is for offline printing.
Why is the canvas size coming out to far larger than I specify in File > New ? How do I get a correct canvas of the correct dimensions with a resolution of at least 400 dpi?
Any advice would be much appreciated. I’ve used Paint Shop Pro for years, but this issue is killing me…
Thank you, thank you, thank you!
Basically, the monitor will display the file at it's "pixel size" not its dimensions. On a Macintosh 72 pixel per inch monitor, here's what happens:
- A 10" wide graphic at 72 pixels per inch will be 720 pixels wide. (10 x 72)
- A 10" wide graphic at 144 pixels per inch will be 1440 pixels wide. (10 x 144)
- At 100% viewing size, the second file will appear twice as large at the first file on the monitor, because it's actually twice as many pixels wide.
- However, when printed out (either on a home inkjet or a professional printer), both images will be 10" wide... the monitor displays according to # of pixels in the image, the primter outputs according to specified file dimensions.
Just set your file dimensions to the correct mm x mm size, set the resolution to the correct print resolution (400 ppi in your case), and then work on the file at 50% viewing size (or whatever viewing size you're most comfortable with).
Freaked me out the first time I noticed that phenomenon, but that's the way it's *supposed* to work. Now take a deep breath... relax... ;)
Getting the pic. in its proper size now shows me how it will look when it is printed out - and it's not good. See:

I've tried various effects in Paint Shop Pro to enhance the photograph, but to no avail.
Is there any way of smoothening it, so I can get rid of those grid-like lines other than by rescanning the picture?
It's currently in the balmy 70-80ºs here... and nice and dry. :)
As for your quality problem... It looks like you scanned the image in from some printed material? Does your scanner program have a setting specifically for halftoned images? Mine offers these choices of "input" material settings: Copy/Fax, Black & White Photo, Color Photo, Color Halftone, etc.
If your scanner doesn't have a specific setting for halftone images, it sounds like theperlyking has suggested the PSP equivalents of exactly what I'd do in PhotoShop...
