New inkscape extension: Export PDF in CMYK and TIFF in CMYK

Postby jonata » Fri Sep 03, 2010 10:33 pm

Hi there!

I'm developing an extension for exporting PDF files with the CMYK colorsystem, using the last version of Uniconvertor.
It's not 100% yet. Text doesn't run so well, just paths. Special effects (blur, filtros...) even so.

http://wiki.softwarelivre.org/InkscapeB ... tarPDFCMYK

If you want to generate a PDF from a Inkscape draw that have objects with special effects, add to the object "ID" the characters "cmyk" (To do that, select the object, click with right button on it, "Object Properties", add the characters "cmyk" on "Id" textbox and click "Apply").
The extension will find the objects that are named with "cmyk" and convert it into CMYK bitmaps.
Due to a technical issue, there isn't the possibility to generate PDFs with CMYK + alpha bitmaps. And it runs only on Linux.

Finally, here is another extension for exporting TIFF in CMYK colorsystem:

http://wiki.softwarelivre.org/InkscapeB ... arTIFFCMYK

Please test and send me feedback.

As a part of the Brazilian Inkscape Users Community, it's in portuguese, but I want to translate it soon.

Thanks very much!

WOW!
I'm sorry that I can't test for you, because it's a bit over my head :oops: . But I just wanted give you a shout-out -- THANK YOU!!
We get so, SO many messages here asking for this, so I know that it will be well utilized by many users, when finished. By posting here, others will see it and maybe like to help you with the coding, besides just giving feedback (fingers crossed :P )

Thanks again :D

Thanks brynn

As I said, just using and sending me error messages is already helping me. Of course, this is not "the" solution but...
The Brazilian Inkscape mailing list have a lot of messages regarding CMYK too. So, it shows that it's almost a must.

Thanks.

Hi jonata.

In ExportarPDFCMYK
Let's try to replace the "device-cmyk" to "icc-color".

might be due to the svg spec. reference to icc profiles in a document?

Currently Uniconvertor ignores color profiles of SVG, but the icc-color corresponds to the specification 1.1 and is already supported by inkscape for color in CMYK.
Editing the "ID" would not be necessary.

In the future plan to add option "- forceCMYK"

    The use of "device-cmyk" is just a trick to uniconvertor generate PDF in CMYK... the generated svg code doesn't need to follow the "specifications", I mean... the user will not see/use the svg, just uniconvertor.

    Anyway, I'll test if there is some difference in the final process... my worry is if uniconvertor will consider "icc-color" the same way as "device-cmyk"

    I can't comment on UniConvertor and whether it needs to be "tricked"(?).

    There are other reasons not to base a workflow on 'device-cmyk' as explained in the previously posted links:
    #444021, in the comments:
    (…) device-cmyk should almost NEVER be used. First of all, there is not really such a thing as "the generic CMYK color space". By definition CMYK color is very device dependent, and without the context of a specific instance of a specific printer, the numbers themselves are meaningless and dangerous. That is mainly since the exact same numbers are almost guaranteed to create a different output each place they are used.

    Someone *needs* to know a specific target for CMYK to be able to use CMYK. (…)

    (…) uncalibrated device color should avoided for any normal work. The main expected use case is for someone sending raw data to a printer in order to be able to print swatches to measure and create a printer-specific ICC profile from.

    #542346
    One first problem is that device CMYK is not the type of CMYK that the average end user should be dealing with. What they actually need is ICC CMYK tagged to some standard/common profile (such as SWOP).

    Uniconvertor doesn't save PDF in CMYK by default, so I need to use this "trick" in SVG code.

    There are other reasons not to base a workflow on 'device-cmyk' as explained in the previously posted links:


    Please understand me. This is not an extension for producing "SVG in CMYK", it's for producing PDF in CMYK. The extension doesn't apply to the original SVG any kind of "device-cmyk" or "icc-color". This piece of code comes just to Uniconvertor generate the PDF in CMYK, because actually there isn't any other way to have Uniconvertor generating PDF in CMYK, just RGB. Keep in mind: the generated SVG with "device-cmyk" is just a workarround for Uniconvertor while it doesn't have the option to save PDF in CMYK.

    just a thought, to make the object id (label) more user friendly, "device pdf2cmyk". The thought is to "remind" the user this is a pdf based operation.

    I did get your point - my point OTOH was questioning the usefulness of producing generic 'CMYK' files without context (like standard/common or printer-specific ICC color profiles to support a color-managed workflow). But I'll leave the discussion to Inkscape users with more experience in "professional prepress work"... ;)

    Editing the "ID" would not be necessary.


    Editing the ID is just to generate bitmap of certain object. All the other objects are automatically converted in "CMYK"

    Hi there!

    I updated the extensions, they are a bit more fast and with less bugs. For more details, try to read the following pages from InkscapeBrasil.org's wiki:

    http://wiki.softwarelivre.org/InkscapeB ... arTIFFCMYK
    http://wiki.softwarelivre.org/InkscapeB ... tarPDFCMYK
    http://wiki.softwarelivre.org/InkscapeB ... rtarJPGICC
    http://wiki.softwarelivre.org/InkscapeB ... rtarPNGICC

    The only one of them that doesn't runs on Windows is the no updated version of "TIFF in CMYK". I'm not able to get it working with the windows "shell" version of inkscape - or python is not able to talk with it.

    Thank you for the attention, I'm waiting your comments.

    hi,

    i'm not very technical at this, but i am curious for it to work, because i'm using inkscape and all other free software for my job. Since inkscape doesn't support the export to PDF in CMYK, i'm all in favour of your work done here.

    But i need some help. I've gotten as far as installing the 2 scripts into the folder mentioned, and installing Uniconvertor. When i reopen my draw in inkscape i add the characters 'cmyk' to the object properties' ID. I don't know if i need to do this for each object in my draw or on the overall draw? Furthermore i don't quite know what is meant with 'device cmyk' and 'icc color'. When i want to export, i notice there are 2 options to my 'save as' list, namely 'CMYK tiff' and 'CMYK PDF'. When i try the last, i get following error message:

    The last version of the extensions recognises the layer with ID "background", not "cmyk" as before. Try to name the layer that has special effects with the word "background".

    Thanks for using it!

    I have installed the extension in Inkscape 0.48.0-1ubuntu1 and tried to save me design with bitmap, text and shapes to CMYK PDF and got the following error. Can this be fixed please? I'm willing to test improved implementation because Inkscape simply has to support at least CMYK exporting.

    Hi Pander

    Nice to know you tested the extension.

    Did you check the extension to "rasterize" special effects? If so, did you put them to a new layer with the id "background"?

    Thanks!

    Hi there

    I've translated the brazilian wikipage of the extension into english on Inkscape wiki. Here you are:
    http://wiki.inkscape.org/wiki/index.php/ExportPDFCMYK

    The english is not so good, so I'll check it soon.

    Thanks!

    Hi there!

    Just to say that I updated the extension: no need to put every special graphic on a separate layer.

    Thanks!

    Please test and send me feedback.

    As a part of the Brazilian Inkscape Users Community, it's in portuguese, but I want to translate it soon.

    Thanks very much!


    Hi, guys,

    here is a simple icc-color support patch:
