Tips and advise for alternative ways to generate QR codes from 'down under'.

I received and email stating that what I was claiming with regards to QR code quality and printed matter was not true, and wrong. It was bold and held merrit so I asked to publish it here as alternative to making and using quality QR codes.

My thanks to Tremain Jennings for the input and allowing me to share these solutions with you.

Your article on QR code file formats is wrong.
http://blog.qr4.nl/page/QR-Code-File-Formats.aspx

You say you need 300 to 2400DPI, this is true for 1 Bit images with curves or angled lines (like a circle or triangle) however a QR code doesn't have curves, it’s made of only horizontal and vertical black lines and because of this you do not need 300+dpi resolution. A circle or triangle at 72dpi would have jagged edges, however a circle or triangle at 600+DPI will have smooth edges.

Many QRcode tools output at 96dpi RGB PNG file, this resolution is fine for PRESS, however you will need to convert to CMYK, delete the CMY channel (make them white) and bump up the K channel (via curves) so it's 100%. You don't need a 300DPI QRcode.

To confirm my point, please feel free to import what you call a 'low res' QR code image into InDesign, then increase the size to 500% to amplify any issues, print your separations and you will see that it reproduces perfectly! (if it looks blurry on screen, change your display to high resolution)

Here is an example of a QR code at 96DPI and the same 96DPI image scaled and rotated.
The image is a CMYK TIFF with the CMY channels deleted and the K channel at 100% black. You will see that it reproduces perfectly!


Not satisfied? Here are the steps to change a 96DPI (RGB) QR code to a 1200DPI, 1 Bit TIF.
1) Open in QRcode in Photoshop
2) Change Image Size to: 1200 pixels/inch (up to 2400DPI if you like) - ensure the document size is what you require - make sure you resample the image using 'Nearest Neighbor' (NOT bicubic).
3) Change color mode to grayscale
4) Change color mode to Bitmap and use method 50% Threshold (just to be sure).
5) SaveAs TIFF

What is important to consider with QR codes?
1) If it's RGB, convert it to CMYK and delete the CMY channels and ensure the black is 100% and nothing less.
OR
convert it to a bitmap as stated earlier.
2) There must be ample white space around the outside of the QR code if the background colour is not contrasting enough.
3) Scan the QR code with as many devices you can get your hands on.
4) Don't make the QR code too small because it works fine on your new iPhone, older devices might not be able to scan it.
4) Make sure the QR code contains the correct URL
5) Use www.goo.gl or similar URL shortener to make the QR code smaller.  The longer the URL, the larger the QR code.

How to create a QR code
If you need to create a QR code, try using www.qrstuff.com
If you use www.goo.gl the site will create the QR code for you.
If you need to create QR codes automatically on your website as a back-end process try http://platform.twit88.com/projects/mt-barcode to create the code and then use http://www.imagemagick.org to convert the image to a 1Bit TIF.

Any Place, Any Time, Any Size QR Codes

Need QR codes the size of skyscrapers or those that need an electron microscope to be readable, then vector QR Codes are what you need.

Why?

Vector QR Codes, also known as line drawing barcodes, remain perfectly clear at any size they are used. This in contrast to bitmap or pixel based QR codes that degrade proportionately to the size they are enlarged. So if you're in the printing industry or want your QR codes printed, these are the sort of QR codes you want to get.

Less is More

Small file size has great benefits if you need to make thousands at point A and get them to point B as soon as possible because B is waiting. A typical problem for dynamic data printing processes. This puppy is a native and compressed PDF QR Code generator, harbouring the best of breed on all aspects. It's small, yet can be created at any size without loss of fidelity. Print ready for any digital or conventional press.

Is this possible?

It's not only possible, it's reality, try it yourself!
