QR Code Fonts

QR code symbols and font glyphs

Imagine being able to place your favorite QR codes in any document anywhere at the touch of a key on your keyboard.  Considering that printed QR codes have the most intrinsic value it nearly seems fundamental that these should be available for publishing at a key stroke.

Having your QR codes as a font means you can publish them in any document at any time and at any size. So whether you place your vCard QR code at the bottom of all your stationary, or as a designer put your Facebook like QR code on a giant poster, the same QR font set is perfectly suitable. This is because fonts are scalable to any size, from micro printing to massive billboards the font will always give a perfect sharp representation.

How QR code fonts work

A QR code is a two dimensional bar-code built with square blocks. Each block is made of four lines and then filled with a colour, preferably black. All the blocks of a QR code are placed as a 'glyph' into a 'font' and assigned to a specific letter of the alphabet. Consider placing your Twitter QR code under the letter 'T' and the Facebook QR code under the letter 'F'. In this way it is possible to place any QR code of any complexity under any key of your keyboard.

Even designer QR codes can be used as a font provided the design in monotone (one colour)

QR code font example

Provided is a free downloadable TrueType QR code alphabet font that instead of letters and numbers has a QR code that represents each letter and number (ASCII only for now). I don't think it idea to use to publish your next novel, but does show that QR codes are perfectly at home and usable as a font.

A world of difference between QR codes intended for computer screens, video and TV and those used for printed matter.

Choosing the right QR code colour

And it even applies to black and white QR codes too. There are two basic colour models that are interesting for QR codes. The one for 2D codes displayed on computer screen, used in video or on television. This colour model is called 'RGB' (Red Green Blue). The second is used in the printing industry for printing coloured text, images, graphics and of course QR codes as well. This colour model is called CMYK (Cyan Magenta Yellow Black).

These two colour models are complete opposites of each other. Lets see how this works....

RGB RGB

Is used for radiant media like computer screens and television it is made up of three basic colours : red green and blue. If all colours are not used (switched off) you have a black screen. As you add more of each colour it becomes lighter. Adding 100% of each colour will then give as result a white screen. Thus the more colour, the lighter it shows.

CMYK 

Used for reflective media, like white paper. It is made up of four basic colours with one (Black) being an interesting one. Here no colours (or ink) means a white sheet of paper, and the more of a colour you add the darker it becomes. It is thus the exact opposite of radiant media. using Cyan + Magenta + Yellow should give us black, but instead it turns into a very dirty bark brown, and costs a lot of ink from each colour to achieve this. So black is added as fourth colour to ensure a solid black colour and minimize the amount of colour ink(s) needed to achieve this.

 

RGB Colour Model CMYK Colour Model

From this we can see that printing QR codes created with a RGB colour model may look great on your screen, but your printer does not want them as even if your QR code is black and white, the black will translate to 100% cyan, 100% magenta and 100% yellow which is exactly what you printer does not want.

So next time you create a QR code, think first where it is going to be used, for display on a screen or for printing and choose the correct colour model to get the right results. If required for both media it is advisable to generate it twice using both colour models.

The thin line between quality QR codes

Most generators found on-line and offline create 'bitmap' QR codes, these images or pictures are made from a series of dots called 'pixels' and generally intended for display on a computer screen or monitor. Each image has just so many dots as is required to display the image at a set size. But what happens when you need a QR code to display perfectly no matter what size you want it.

The difference between a bitmap QR codes and vector QR codes

Below are two identical QR codes, one is bitmap and the other is a vector representation, both generated at the same original size.

Comparing the two different types of QR code files by zooming in clearly shows that the bitmap looses clarity and becomes fuzzy. This may explain why Blackberry QR Code readers have so much trouble reading these codes ;)

Bitmap QR codes are great for displaying on a screen, but often fall short when it comes to being used with most types of printed collateral.

Why do the vector QR codes retain their clarity under any magnification

The reason is simple. Vector QR codes are made of lines and then filled in with ink. so it does not matter whether a QR code bock is 1 mm by 1 mm or 1 m by 1 m. In each case a box is drawn to the required dimensions and then filled with a colour, leaving a perfect clear square no matter how large or how small you make the QR code.

Interesting to note is that this generator takes the 'Quiet Zone', the required border around the QR Code into account
Click on the image below to download the EPS (Encapsulated PostScript) file that generated this QR code.

PostScript Vector QR CodeThe QR code about were created by the generic matrix to vector processor developed by QR4 which is an industrial QR code generator capable of generating variable and dynamic QR codes faster than the print speed of any digital printer, and is also available on-line for 24/7 use for all our clients.

Next time your need to print QR codes, require quality results, a happy printer, and QR codes that just work better, use vector or Postscript QR codes, you will be surprised at the quality and efficiency.
