What is the PTG Extension?

ArtRage paintings all use a unique, proprietary, file type, the .PTG extension. The file type can only be opened by ArtRage and can be used across all the different editions (including the free demos and iOS versions).

The reason we use a special file type is because ArtRage needs a way to preserve all the unique traditional painting aspects of the program, such as paint thickness, canvas texture, realistic colour mixing, lighting and how the different media should interact. It also records more standard attributes, such as layers and transparency, and preserves ArtRage-specific attributes such as pinned References, tracing images and symmetry.

What does “PTG” stand for?

PTG means “Painting” (PainTinG).

CMYK Colors

Limiting to CMYK while drawing would cause inaccuracies and poor results in paint blending because the range of colours available in CMYK is smaller. We need the largest range of colour values available for generating partial blend results during paint mixing calculations.

When you convert, the application (Photoshop in this case) converts any non CMYK legal colours in your image. If you painted in CMYK you’d get the same limited palette. This is why ArtRage works in RGB, we try to avoid reducing your colour palette as much as possible.

Why doesn’t ArtRage convert from RGB to CMYK when the painting is finished?

Converting from RGB to CMYK is an advanced operation that ArtRage is not currently suited for. We recommend using programs that are specifically designed for CMYK to convert the final picture.
