Dot gain

Printing is widely affected by dot gain, this is shown when prints come out darker than expected. This is the result of halftone dots increasing in diameter during the prepress. This happens while preparing media and machine’s optical and physical properties for the printing process. Mechanical and optical are the two main types of dot[…]

Raster vs Vector

Raster A raster image is a picture made out of a huge amount of pixels (one dot on a screen that represents one colour). Raster images are very commonly seen in our everyday life as these can vary from photos to many other pictures found in media created by programs for producing and editing raster[…]

Pantones

The pantones (or PMS – Pantone Matching System) are an assortment of colours that are created by ink, printed using a single run. They have a numbering system so that every individual colour is unique and can be identified easily. This system was created to help manufactures everywhere to communicate the specific colour they need[…]

Pixel Values

  Pixel values represent the colour and how bright a specific pixel in an image is. Pixel value varies according to certain images. Binary images only need a 1-bit number stored for every pixel (black or white) whereas gray scale images have pixel values of only one number to indicate t he amount of gray needed[…]

ICC Profiles

The acronym ICC profiles stand for international colour consortium. These profiles are information stored in various devices that are capable of outputting or inputting imagery. They are recordings of how many colours the input/output devices are capable of capturing or showing. Such examples of these devices could range from any type of output devices (mobiles,[…]

CMYK vs RGB

RGB and CMYK are the two colour models every designer will at one point work with. They are different modes of colours both used for their specific task. One is used for digital work and the other for printing purposes.   RGB   The acronym RGB stands for red green and blue. These are the[…]

Colour Depth

Bit depth or better known as colour depth is referring to the number of bits presented in one pixel of colour. Bits represent all the 0’s and 1’s that specify a certain colour. Different shades of colours can be displayed with higher bit rates. You can calculate how many colours there is in a bit[…]
