| Summary | 0002167: Spot colours | ||||
| Description | Support for spot colours is important for many people to get full use out of Scribus. There are work arounds right now (wiki.scribus.net/index.php/Simple_Scribus_Spot_Colour_Printing_method) but they're not exactly convenient. If we support multiple colour formats in future, say CMYK, RGB, RGBA, etc, we could also support "named colours" that have a viewing/printing colour associated with them but are distinct from normal multi-channel colours. In other words, spot colours. Once we support real spot colours in the app's internal colour model, we could extend this to support true spot colours in TIFF, PS, EPS, PDF and PSD imports and exports. There's still the PANTONE issue to consider, but I'm not sure that matters too much - I don't think anything requires our spot colour names to be PANTONE ones, or stops us offering user defined named colours so the user can import whatever they want. | ||||

A useful conversation on #ghostscript that I jumped into when I noticed it was about spot colour in gs: stefan911 Gigs2: thanks Gigs2 stefan911: this is a serious one for us, if we use parentheses it limits us to 4 colors, if we don't use them, we can't have colors like "Dark Blue" so our development is effectively stalled ringerc Hmm ... support for > 4 colours in gs? Is this related to spot colour? ringerc If so, this is something I'm interested in knowing more about re gs as well. Gigs2 ringerc: yes, tiffsep device supports up to colors, 4 spot colors and CMYK stefan911 I thought spot colors used pantone numbers or other ink system #'s rather than names like dark blue, tells you what I know Gigs2 stefan911: they usually do Gigs2 stefan911: but "Pantone 121 CV" still need parentheses adcoby gigs: For spot color names, use either parenthesis (i.e a PostScript string) or a leading slash (i.e. a PostScript name). Do not do both for a single colorant. Gigs2 adcoby: ah, excellent Gigs2 adcoby: I was hoping it was somthing stupid Gigs2 thanks ringerc Gigs2: That's great. Seems to be in 8.51 too. Now I need to look into what's involved in producing gs-friendly spot colour PS from Scribus. Gigs2 cool adcoby In Postscript and PDF, spot colors are defined using the Separation and DeviceN color spaces. adcoby In Ghostscript, only a few output formats support anything besides Gray, RGB, or CMYK. ringerc Good to know. adcoby For these devices, spot colors are converted to Gray, RGB, or CMYK by using the tint trasnform function in the color space. Gigs2 adcoby: psd format will carry spots through right? adcoby The psdcmyk and tiffsep devices, produce output that actually has the spot color info. Gigs2 adcoby: closing bug, thanks ringerc Mind if I note this conversation on the scribus bug tracking spot colour? ringerc You folks know some useful things :-) ringerc eh, don't worry ... should just note the important info anyway. Gigs2 I don't care Gigs2 you can copy my bug report, it notes the syntax to select spot colors adcoby please do what you want with the text here. ringerc Thanks. Gigs2 bug 688178 for gs Gigs2 that contains a lot about the correct way to select spot colors for output Gigs2 and how not to do it :) |
