Using Tone Curves
Whether you are Screen Printing, heat transfer printing or Inkjet-to-Garment
printing, a common dilemma is that images tend to get a little “muddy.” If you
have a fi le with lots of detail in the shadow areas, this will probably be lost when
printed so you need to adjust the “density levels” of the image. In FastARTIST,
go to the Bitmap dropdown menu, and then select CMYK Color Adjustments >
Curves . In Photoshop, go to Image > Adjustments > Curves .
The Tone Curve is a very powerful tool that allows you to adjust speci fi c tonal
areas from the lightest “Highlights” to the
darkest
“Shadows.” By placing your cursor in the
middle of the “Midtones” curve and dragging
the mouse up or down, you can
lighten/darken the medium, or Midtones, in
an image.
By clicking on the very top corner and
dragging the mouse in, you can make the highlights
lighter
(Photoshop). Play around with the Tone Curve and
see what happens. A good curve for fl at images is a
slight “S”, where you lighten the highlight area (35%)
and darken the shadow area (75%).
In later versions of Photoshop (CS through CS3),
similar adjustments can be made using the Shadow/
Highlight dialogue under Image > Adjustments . Make
sure you click the “Show More Options” check box for
additional settings.
Bitmap Editing in FastARTIST
Photoshop is always in bitmap mode
because it is a pixel-based editing program.
FastARTIST (along with CorelDRAW and
Adobe Illustrator) defaults to vector mode
when you launch the program, so you will
need to fi nd the bitmap editing tools in
these programs. In FastARTIST, double-click
on the image. That changes the top
Toolbar icons to standard bitmap editing
mode (very similar icons to Photoshop).
