I looked at what Epson have to say online, apparently sRGB is a term for contrast increase... I guess they are trying to come up with a system which will work for professionals and novices (and managing to confuse everyone in the process) EPSON Standard (sRGB) - Increases the contrast in images. Use this setting for color photographs. Adobe RGB - Matches image color to the Adobe RGB. EPSON Vivid - Select this setting to enrich the blue and green tones in prints. Because this setting reproduces blue and green tones that cannot be displayed by your monitor, your prints may differ from the screen image when this function is selected. Charts and Graphs - Intensifies the colors, and lightens the midtones and highlights of an image. Use this setting for presentation graphics, such as charts and graphs. Best Matthew

To my knowledge the printer color management can not detect what the assigned color space is in the data it gets from the application you print from. So it offers two choices of color space and expects the user to send image data with the corresponding color space assigned. The application should not perform color management but allow the choice: Let Printer do color management. No rendering in the application should have effect then. The image data should still have the color space assigned up to the the printer color management but I doubt it will be recognised. The printer color management has a default rendering but I doubt it includes BPC. Based on experience with HP Z3100 and Z3200 drivers. The PS driver of the last model offers some CMYK assigned spaces as choices too.

Dear all I have struggled to understand a setting in the Epson printer driver for many years. (Yes my life is that boring). It seems to be a fairly universal setting (R2400, 3880, 4800) When using Printer Manages Colors > Print Settings > Color Settings, there is the option to select EPSON Standard (sRGB) or Adobe RGB (Along with Vivid and charts and Graphs). This setting does seem to have a slight effect on the printed image. An ARGB image seems to print slightly more accurately when the setting is Adobe RGB (Using the Pixl test image).
Does anyone know why it is there and what it is for?
The vivid etc suggests to me that it is some kind of rendering intent, if so why is it called sRGB etc and why have 2 rendering intents in the workflow (The rendering intents are not greyed out in the Photoshop Printer Window)?
