I am making a Tarot deck and have scanned and worked on 79 cards and now the printer says they need the DPI at least 300 and my cards are at about 96 DPI. I have done alot of work on the cards and don't want to start over.

The dimensions of French Tarot cards are 60 x 112 mm.

For a resolution of 300 ppi, you need 709 x 1323 pixels.

What's the size of the image in mm or inches?

The resolution figure itself (300 pixels per inch) does not mean anything without knowing the size in mm or in.

If you have enough pixels, you can use the Image >> resize command.

If you don't have enough pixels, you can 'upsize' by adding additional pixels, that's called 'resampling' (see the resample box). But that won't add any detail or quality to your images.

My cards images are 3 in by 4.75 in. The ppi is 96. I thought that was the
same as DPI. Not sure where to find the DPI for the cards. I scanned them at
1200 DPI on my printer originally but when I went to print them on my
printer they said they were less than 300 DPI. Now I have a new computer but
the same printer and I am not getting that message when I print them.



I have resized all my images already, they were larger.



You said:

" you can 'upsize' by adding additional pixels, that's called 'resampling'
(see the resample box). But that won't add any detail or quality to your
images"



Why would I do this if it doesn't help the quality of the image?



Thank you for your help,

Carolyn

Carolyn13,

DPI = dots per inch. This is controlled by your printer.

PPI = pixels per inch. This value refers to the resolution, as delineated in the previous post by MichelBParis. I doubt that you you can adjust the setting in the scanner to a higher output.

However, if it is truly an issue as it relates to DPI, do the following:

Follow these steps to change your printer’s default settings:
 
1. Type “Devices” into the main search bar at the bottom left of your screen
2. Select “Devices and Printers” from the results list
3. Right click on the appropriate printer icon
4. Select “Printing Preferences”
5. Change print settings, click “OK”
6. Ready, set, print!

This works for me:

Upsizing resolution of a 72 ppi image. Turn resample image OFF, type in the desired resolution and hit OK. Then print. Your images are 96 ppi.  This method should work for you too.

Really, start over. There are clever tricks that may make it slightly less bad, but your printer is trying to save you from an expensive disaster.
