I must be able to create a PDF with specific "color" codes for Roland printers.

specific code :

  • RDG_GLOSS
  • RDG_WHITE
  • CutContour

so if I understand correctly ;)

the PDF carries a JPG image and in addition information such as rectangles with a specific color code such as "RDG_GLOSS"

I work in PHP and use TCPDF,

I don't know if TCPDF can allow to use specific chromatic spaces,

I can use another library than TCPDF as long as it's PHP, it's the only constraint ^^

examples PDF with AI : https://mega.nz/#F!OQwzABTA!WTSzA3m3uVE6TDe6uWDN2Q

Information can be useful: SVG spot color and cut lines

the solution may be spot colors : https://tcpdf.org/examples/example_037/

but I don't know how it works.

Thanks in advance;)

Spot colours sound like they could be the answer. 

$pdf->AddSpotColor('My Red Spot Colour', 0, 100, 100, 0);

The numbers are CMYK, so you'd need to know what the CMYK values for each printer code are. In my example, 0% cyan + 100% magenta, 100% yellow, 0% black, which gives us red.

  • You just gave me an idea. The printer only pays attention to the name of the color and not to the color itself. there can be 2 RDG_GLOSS with 2 different colors and this is not a problem. I'll try this: $pdf->AddSpotColor('RDG_GLOSS', 0, 100, 100, 0); $pdf->Text(73, 100, 'RDG_GLOSS'); $pdf->AddSpotColor('RDG_WHITE', 0, 100, 100, 0); $pdf->Text(73, 100, 'RDG_WHITE'); $pdf->AddSpotColor('CutContour', 0, 100, 100, 0); $pdf->Text(73, 100, 'CutContour'); – S8N May 09 '18 at 14:16
  • let me know how you get on! :-) – delboy1978uk May 09 '18 at 14:16
  • I confirm, it is the name of the spot that is important for the printer, the color is not used – S8N May 14 '18 at 14:55
  • glad you sorted everything! :-) – delboy1978uk May 15 '18 at 09:15
