Grayscale is the correct Color Mode for preparing a Raster Document for Rub On Sticker Decal Transfers. Take advantage of the significantly smaller file size to increase the resolution of the document which will enable the reproduction of thinner text font weights, smoother curves, and visually sharper graphics that would otherwise appear bold or bloated. A resolution of 300DPI is not adequate for text and smooth curves. A minimum of 600DPI is required to produce smaller graphics, however, we recommend 1200 DPI.

We receive many documents in the RGB Color Mode that we then have to convert to grayscale. The File Size of a Grayscale Document will be up to 4 times smaller than an RGB document. This will make the creation, editing, saving, storing, and uploading of the file significantly quicker. The RGB color model uses 3 Channels of color, Red, Green Blue to render a very large range of colors enough that it is used for photographs. Storing, calculating onscreen rendering of all the permutations of 3 colors uses up to 4 times the computer processing power than that of the 1 channel color mode Grayscale.

While many Raster Software Applications usually support a few to several Document Color Modes, if your Sofware application does not support Grayscale then an alternative would be Bitmap BUT the minimum resolution would likely have to be 1200 DPI, while a resolution of 2400 DPI should produce smooth sharp details. We hope to create a test to verify the feasibility and result sof working with such a high resolution and post the result here. A lower resolution will create the stair steps or jagged saw tooth look for any curved object and any lines that are at a slight angle. If Grayscale is not available and bitmap is not practical, then RGB would be the choice if other modes such as Indexed color is not available.
