Graphics (GOCA)
Introduction
The Canon imagePRESS C7010VPS series support the complete GOCA DR/2V0 subset. Some
additional GOCA functions are also supported.
Line Width
The GOCA line width is an integer (Set Line Width drawing order) or decimal (Set Fractional Line
Width drawing order) multiplier of the normal line width. The normal line width (NLW) is
approximately 0.01” or 10 mils (1 mils = 1/1000”).
With a 240 DPI print head resolution, the normal line width would be 2.4 pixels. After dropping
the decimal, a one NLW wide line will be printed with 2 pixels or 8 mils instead of the ideal 10
mils. With a 300 DPI print head resolution, the normal line width is 3 pixels and with 600 DPI the
normal line width is 6 pixels.
Patterns and colours
The appearance of the GOCA fill patterns is printer specific and may vary between different
printer models. Applications printed on other IBM printers may therefore look slightly different
when they are printed on a Canon printer. The GOCA patterns are rather coarse structures, not as
fine as a colour screen. If you combine a GOCA pattern with a GOCA colour, the result will look
different on different printers.
Image resolution
GOCA is a fully resolution-independent architecture; except for the GOCA raster image. A GOCA
image is similar to an old IM1 type image, i.e. an uncompressed bitmap. Old GOCA images,
created for either 240 or 300 DPI, can therefore only be printed with that resolution.
