Brother GTX-4 Instruction Manual page 58

About color mode (color space)
The GTX-4 printer is a printer of RGB type.
Be sure to create image data in RGB mode, and always set the color space (input) you use for such data to sRGB
(sRGB IEC61966-2.1).
<TIPS>

When such application as Adobe and Corel is used, there are instances in which an image in CMYK mode cannot reproduce the
color that is intended.

Even for an image in RGB mode, a similar color reproduction failure occurs when other color space than the specified one, such
as Adobe RGB, is used.
About print layout
When using an application other than Graphix Lab, specify the platen size that uses the paper size specified in the Print
menu, and confirm the print layout.
Moreover, use the "Brother GTX-4 FileOutput" printer driver for file output, then display and check the print preview.
<TIPS>

In order for a print image to be oriented properly at all times, it is advisable to set the GTX-4 printer to the [Set as default printer].
How to create white data
For such a portion that you wish to print out in pure white color with white ink, fill it with RGB=254.
<TIPS>

The RGB=255 is treated as a transparent color (non-printing color).

When it is likely that RGB=255 is contained in an image as seen in photographic data, check to see if such color is contained or
not in the print file (ARX4 file).
About ARX4 file
Use the "Brother GTX-4 FileOutput" printer driver for file output in order to save your print data in the ARX4 format.
When your print data is saved in the ARX4 format, its information and the amount of used ink will be able to be reviewed.
<TIPS>

When performing file output, be sure to use the printer driver, "Brother GTX-4 FileOutput". If file output is performed using [Print to
file] command that is supplied with each application, there may be some cases where the file extension cannot be saved as .arx4,
or the file destination cannot be specified.

The GTX-4 printer cannot print out the print data that has been created for the GT-541/GT-782/ GT-3 series.

If you make a printer driver setting from the Control Panel of your PC, such setting sometimes will not take effect in each
application. For this reason, verify that your printer driver has been set up properly before you begin printing.
