My understanding is that "Save as Adobe PDF" uses the PDF Distiller to access more options. When I "print" the PDF I have the option of "Save as a PDF" or "Save as Adobe PDF". I have to do this process on a large number of projects over the next couple of years. However, it would be nice if the PDF file was correct without having to compensate for the error. M workaround is to use Photoshop to adjust the size by 100.10%. Not much, but enough to make the cuts of the printed image inaccurate. For example, a line 410mm long in CAD is 409 when the PDF is imported into Photoshop. It's the lines in the CAD image that are the wrong size. When imported into Photoshop the image field is the correct size - 431.80 X 279.40 It turns out that 100.10% is the correct number, or at least my best estimate. "Original line" represents the image that is too small, and "Enlarged" shows that it must be stretched to be the correct size to match the laser cut. In the example below, the PDF has been imported into Photoshop. The lines on the right represent where the machine would cut, off by about 1mm Fail. The image below shows the results that came back from the company that does my laser cutting. How accurate is a PDF when it is created? The folks at TurboCAD say the issue would be with the Mac's creation of the PDF file.
This leads me to believe the problem occurs when exporting from TurboCad, not when importing into Photoshop. If I open the TurboCad PDF in the Mac Preview app, export it as a jpeg or tiff and open it in Photoshop, the same thing happens. It was off by about a millimeter on the right side.įor some reason, Photoshop imports the image ever-so-slightly undersized and it needs to be enlarged 100.10% to be corrected. I had a hundred 11"X17" (279.40mm X 431.80mm) test sheets printed on an off-set printer and the laser cut did not line up with the graphic. Later, the CAD drawing will be used to do the cutting of the printed sheet.
The workflow involves exporting a PDF of a 2D drawing, and opening it in Photoshop to create the artwork. I am using TurboCad to design a graphic that will be laser-cut from a cardstock sheet.
