Draw - PDF settings

When I convert a 2 page document, 1 side colour 1 side B/W, to pdf and send to a photocopier via the pc so it is printed the photocopier counts each page as colour, as we are charged for each page we print and colour is much more expensive I wondered if anyone knows why or how to prevent it.

Word documents count correctly but not those via draw. 

I spoke to the photocopier tech guys today and they can't explain it but also don't know draw.

I also have to turn the second page upside in draw otherwise it prints upside down -  but not from Publisher is this a pdf/draw mismatch? 

  • The upside down second page is probably an error choosing the duplex setting.

    In CorelDraw, click on the preferences button in the print screen, alongside the printer dropdown. But after that, every printer has a different layout. Here' mine:

    In that duplex section, you see that apart from off there are two possible duplex settings. Other printers use words instead of graphics, maybe a choice of "long edge" or "short edge" duplexing. Whichever you currently have, you probably need to choose the other setting.

    The colour or black and white selection will probably also be on the same screen (in my case, its the panel below the duplex selection). But as far as I'm aware, you can only set it once per document -- there is an inbuilt assumption that all pages in the document are the same.

    In theory, CorelDraw ought to be able to work out whether a page is colour or black and white, then if the printer itself allows it, change the mode between pages. In practice, its probably not quite that simple unless the page is composed exclusively of black objects and greyscale images. And then ... what colour is black actually? Is a 1% deviation from pure grey sufficient to consider the page a colour page or should it be forced to greyscale? It is probably easier for word, which in earlier versions at least had no colour management and supported only RGB colours.

    • Thanks Harry I can live with the duplexing but the colour count is a big problem to a small charity. Sorry it took me so long to get back,
      I made 2 documents with one page colour and one B/W, one of them CYMK 100% and the other RGB set the choice of colour to auto and it still counts both pages as colour. If it did so in Word I would say it's the set up of the photocopier printer but Word works perfectly, so I can at this point only assume that it's either Corel or when I convert Corel to pdf that is the problem. Unfortunately I can't print straight from Corel because the charity doesn't have Corel on their PC.

      I suppose I could download a trial of X7 and see what happens then.

        if you print the PDF using Acrobat, it will print all pages as color. Then, the solution is to print each pages separately, one on color mode and the other on black

      Same here color copy/print is 7,5 times more expensive than greyscale (I expect that by B/W you mean GREYSCALE model).

       

      If I have file with color&greyscale pages then I’m creating PDF with settings:

      output color as native

      no color profile embedded

       

      Best regards,

      • Unfortunately grey scale is counted as colour in my case because it is made up from the other toner colours. I've tried a few more options, native setting as one one of them but it still counts the b/w as colour when pdf is converted from draw but not from Word. The other suggestion that was made eg; print one side colour and them run them through again for B/W is not practical because you can only do that from the side tray and it will only take 50 sheets a time, too much fiddling for a 4000 sheet run.
        • You can try to check CMS settings (I have Map Grey to CMYK black thicked on)

          • Thanks Mek that setting is ticked.

            If I could only narrow it down to where the problem lies I could perhaps find a solution. As it is it looks like I will have to dump Corel for the most of the charity work I do, which is a shame because now a days it's almost all I use it for since I retired after 20 years of using it.
            • Can you send me test pdf file. Thanks.
