The important point here is to keep the le resolution high enough for the image to remain sharp. It is
generally accepted that a le needs to be at 300 dpi at the nal size in order for it to remain crisp.
In T-Shirt printing, you can get away with le resolutions of 150 to 300 dpi at the nal size.
You MUST know the actual resolution and size of
the image, otherwise you could be working on a very small le
and not know it. In FastARTIST, Import a photorealistic le and
click on Bitmap > Image Size. This will display the actual size of
the image in terms of total X and Y pixels and Pixels per Inch
which is the equivalent of dpi. If the resolution is not sufcient,
enter any changes and click on Apply. Remember that an
appropriate image size should be 150 to 300 dpi.
If the images physical size is too small, resize the image before changing the resolution. After the image
size is adjusted, click on Bitmap > Image Size. Change the resolution and select Bicubic. Click Apply.
In Photoshop, go to Image > Image Size. If it
says pixels per cm, change this to inches and then enter the
image’s intended nal print size. Re-adjust the resolution
and make sure that Bicubic is selected. The physical size
should be the nal print size.
If you have an image that is very low resolution, your only
real choice is to change the image size and resolution. This
is often referred to as “Upsampling.” Photoshop upsamples
the image, but in doing so, it must make calculations where
to place the extra pixels and what color to make the pixels.
Images may have softer edges when upsampled, but they will also be less pixilated! If you can get a
higher resolution le from the client, do so.
CorelDRAW and Adobe Illustrator have similar Image Size functions.
