How Does Creating Client Side QR Codes Affect The Implementation of QR Codes Used In The Future?
How Do I Get A 200-300dpi Vector Version of This QR Code For Print?
This is where things get a little crazy. if you intend to send this QR Code as a part of a piece to a printer, you need to convert it to a vector graphic and ensure that the whites and black are true in the CMYK format (where white is cmyk(0%,0%,0%,0%) and black is cmyk(0%,0%,0%,0%). Because SVG is actually denoted in the RGB color space, converting from RGB to CMYK does funky stuff in the CMYK color space (black don't turn into true black, for example). Here is how you solve this:
First, get your QR Code showing up on the right. Next, click the "Open SVG File For Saving" button below the QR Code. In the FireFox browser, you will be prompted to save a file. Once it has downlaoded and saved, you need to open the containing folder and rename the file to something like "QR.svg". Now, open up Adobe Illustrator. From within illustrator, go to File > Open... and open up the "QR.svg" file you just created. You are now looking at an infinitely scaleable vector graphic, but it uses the RGB color space. We need this in CMYK using true black and white. To convert the color space correctly, select all of the vector elements within the graphic (drag a select around everything) and select... Edit > Edit Colors > Convert to Grayscale. This gets us half way there. Now, select... File > Document Color Mode > CMYK Color. Finally, select all of the vector elements again(drag a selection around everything) and this time select... Edit > Edit Colors > Convert To CMYK. If you now select a black vector square within the graphic, you will see that you have true black, and selecting white will show up as true white. Save this as an EPS file and you have a scaleable QR Code that has the correct CMYK color space using true black and white which can be place within an inDesign Project and sent to your local printer!
