how can i configure color space (CMYK) and output file format (PDF) in the product definition?

As far as I understand, you are asking about configuring output files in the Iframe API. The API comes with the same set of parameters as the query-string one:

...
"rendering": { 
...
  “hiResOutputColorSpace”: “CMYK”,
  “hiResOutputFileFormat”: “PDF”,
...
},
...

Color profiles are configured in web.config using RgbColorProfileFileName, CmykColorProfileFileName, and GrayscaleColorProfileFileName settings.

Information on Iframe API parameters and on how to set up color profiles can be found here: http://customerscanvas.com/docs/cc/reference.htm

Details on how color management works in Customer’s Canvas are discussed here: http://customerscanvas.c...ion-and-proof-images.htm

Well, you could specify these parameters as the third parameter of loadEditor, but we have found the bug and this feature doesn't work. We will fix it to the next release.

In your case that would look like:

CustomersCanvas.IframeApi.loadEditor(document.querySelector('#editorFrame'), {
            surfaces: [{
		printAreas: [{
	            designFile: "DIY6X9ebookOnly300DPI",
	            safetyLines: [{
                        margin: 8.5,
                        color: 'rgba(0,255,0,255)',
                        altColor: 'rgba(255,255,255,0)',
                        stepPx: 5,
                        widthPx: 1
	        }]
            }]}, { 
            rendering: {hiResOutputFileFormat: 'pdf', hiResOutputColorSpace: 'cmyk'}
});

Thanks for the bug report. I will keep you updated.
