Graphic Design & Printing Technology

Cheque printing:-In cheque the number and other coded informations are
printed with an ink containing minute ferrous particles which can be detected
by a Magnetic Ink Character Recognisation system(MICR).

Holograms :- Holography is a process that creates the illusion of three
dimensionality on a two dimensional surface. Today any image or model can
be transferred into holographic foil. There are four holographic effects which
can be captured in a foil image:

1. Holographic patterned foil :- They produce images of depth and a rain-
   bow of shifting colour as the angle of view changes.


2. Three dimensional holograms :- 3D holograms produce 3D illusion of
   objects and seems to rotate in space as the angle of view changes.


3. Multiple plane holograms :- This type of hologram layers two to four
   images into seperate planes creating the illusion of a 3D scene.


4. Stereograms:- They are sophisticated holograms of live moving models
   that incredibly render the illusion of a brief 3D movie on a two dimen-
   sional surface.

Barcode:-Barcode is an optical machine readable code in the form of numbers
and a pattern of parallel lines of varying width printed on a commodity and
used for stock control. Major use of barcode is to automate supermarkets,
libraries, etc.

Barcode reader is an electronic device that can read and output printed barcodes
to a computer.

QR(Quick Response) codes:- QR code is a two dimensional barcode system.
They are made up of black and white squares which are generated using a code
generator. Even a smartphone can be used as a QR code scanner. QR codes are
now used over a wide range of applications including commercial tracking,
entertainment and transport ticketing, mobile coupening and more. It can also
be used in storing personal information for use by organizations.

Practical Actvities

1. Preparation of flexographic rubber plate in your plate making unit.


2. Distingish between offset, flexographic and gravure ink from the collected
   samples.


3. Generate a barcode for a particlar item in yor computer and list out its
   features.


4. Generate and read a QR code for an address using smart phone QR code
   application.
