You will need to instruct the prepress operator to change the colors to spot before proofing and plating.
For two or more spot colors, you can choose other colors, but they will be RGB when you save the PDF file. If you are planning for your project to be a PMS (Pantone Matching System) spot color job, please work using only black as your color space. To find out the difference in RGB and CMYK, please read our blog article “Designing for Print: RGB vs CMYK”>. When you are designing a print media project, your color setup should always be in CMYK. If it is RGB, it will stay RGB once you export it as a PDF file. When you insert an image into your Word document, Word will retain the color of that image. Any other color selection you use will be a RGB value. The Word default text color choice is black. Understanding How Colors Are Treated in Word The placed PDF file can be stretched to make the margins even, but your text and images will be skewed. Placing an 8.5x11 size PDF into a 5.5x8.5 document and reducing to fit will cause uneven margins. Then they will either send the PDF as it is through the impositioning software for plating, or place the PDF document in a page layout program, like InDesign, to enlarge or reduce based on the final size of your project. Printing companies will take your Word document and create a PDF from it. You should not use the default 8.5x11 page size for your document if the final size of your print media project is smaller or larger. If you need to adjust the margins, choose Page Layout > Margins and select one of the preset margins or you can set a custom margin. In the Custom Size box you can enter the width and height of your document. To change your document to a size that is not listed, scroll to the bottom and click More Paper Sizes. There are a few default sizes to choose from including Legal (8.5x14), Monarch (3.88x7.5) and Ledger (11x17). In the menu bar, choose Page Layout > Size. But what if your document needs to be smaller or larger? Instead of centering the information for a smaller size document within the 8.5x11 page, change the page size to the dimensions of your final printed piece. Word is a word processing application, so it makes sense that the letter size (8.5x11") is the default for a new document.
