Hi everyone,
I’m designing a DVD case cover. I’m printing it with my home printer, when I’m measuring it on the paper it larger than it specified in Photoshop. I have tried to check and uncheck the “Scale to Fit Image” but its still not accurate.
My image is : 297x210
Res : 300ppi
Why the measurement on the paper and the document size in Photoshop are not the same? something to do with the printer driver?
Any help?
ThanksYou don't say what the units of the 297x210 dimensions are — pixels, mm, cm, inches, picas, etc. Frankly, those dimensions don't sound right regardless of which you have selected. The dimensions of a wrap-around label (front, back, and spine) are 10.8in x 7.25in, which is 274mm x 184mm. At 300 pixels/inch the dimensions in pixels would be 3240px x 2175px. Your numbers don't even have the right ratio to each other. Create a new document with dimensions of 3240 x 2175 with both set in pixels. Lay out your cover, leaving approximately a 180 pixel segment in the middle for the spine. Print on A4 or Letter size paper, centered, set to 100%, no scaling. Make sure you have your printer set to NOT print "borderless", since this causes the printer to enlarge the image slightly. If you have a "minimize margins" setting, use it, however.

sami1979 May 20, 2009 3:01 AM (in response to Michael D Sullivan)Hi and thanx for your answer.
Sorry I didn’t explain myself well.
I’m printing the DVD case layout inside an A4 composition, in other words I open a new A4 preset in Photoshop(297x210 millimeters + 300ppi) , than I define a 283 X 193 millimeters box layout inside the A4.
After printing I trim it physically to the 274mm x 184mm layout. when I use the ruler I see that even though I define the box it in Photoshop exactly to 274mm x 184mm its measured bigger on paper.
My page size defined as a4. I have double look at my printer setting, there is no scaling or border options active.
Thanx

Zach Zurn Apr 8, 2010 1:26 PM (in response to sami1979)If you are using an InkJet printer, that could be the problem. Inkjets print one line of print at a time. Each paper type has a calibration of how much to advance after each line is printed. Thicker papers advance through the printer at a lower rate than thinner bond paper. What happens is that if the setting for how much to advance after each line of print is off, then the size of your print will be off in that direction.
The setting for this is called (Feed calibration). I am not sure if your printer supports being able to adjust the feed calibration in the settings panel on your computer or from the printers settings screen.
I use 3 large format inkjet printers and run into this problem a lot. When I am printing a 4 foot by 8 foot print, the 4 foot dimension will be totally fine, but the 8 foot dimension will be a quarter inch too long due to the feed calibration being off for that paper/media type.
Hope this helps.
