STUDY PRINT TECHNOLOGY
I am Arunangshu Paul, a Print Technologist having done my Diploma in Printing Technology from Pusa Polytechnic Delhi, with specialisation in Prepress operations. As a fresher in this field I have always faced problems searching for reference materials while studying various topics of the subjects.
Here is my effort to ease the difficulties that I encountered.
Your feedback will be highly appreciated

PRINTING TECHNOLOGY
Printing Technology is the study of various processes involved in printing viz. prepress, press and post press processes. With the changes in the field of printing happening everyday and use of computers & modern technology it is fast grabbing the attention of the youth and motivating them to join the industry. With the advent of technology the speed of printing has improved, so has the quality of printing.
The institutes offering courses in printing technology are a constant source of skilled workforce for printing and allied industry.
In my blog I will mainly discuss OFFSET process of printing though from time to time I will try to update this space with information on various other aspects in printing on a regular basis.
Topics that I will discuss are mainly Typography, Types of Printing, Prepress operations, Press operations.
Types of Printing
Printing types can be broadly classified as:
1. Screen Printing
2. Letterpress Printing
3. Offset Printing
4. Flexography Printing
5. Gravure Printing
TYPOGRAPHY
Typography is the study of types, typefaces and design of text. It comprises of text presentation, its size and proportion on a page and important factors affected by it are text legibility and readability. In present time it goes far beyond paper, books, posters to computer screen.
Some important terms and their explanations to keep in mind before going ahead with the study of typography
Typeface – A set of characters/alphabets of a particular style for eg. Times Regular, Times Bold. Here it is of utmost importance for a printing student to keep in mind that Times Regular, Times Bold, Times Italics all belong to same typeface family but are different typefaces.
Font – Essentially a computer terminology which implies software implementation of a typeface. There are Mac/PC fonts of different types like Postscript Type 1(PS Fonts), TrueType (TTF), Opentype (OTF), Unix Bitmap Font etc.
Printing Type – Made of metal, wherein a piece of metal has the alphabet in relief in reverse form. Though the use of metal printing type has reduced over passage of time but has not been rendered obsolete.
Readability – Defined by writing style, typeface (serif, sans-serif)
Legibility – How quickly the reader recognizes type. Determined by typographic features like typeface, type size, spacing between lines/characters, paper color, ink density.
Here is an important diagram, please observe carefully as it will help us to understand better other related terms
Baseline – The imaginary line on which the text base sits as shown in the picture above. The baseline is an important aspect in typography, as it gives coordinates to align the text at the base.
Leading – Space between two lines, it can also be described as the interlinear space between two baselines also known as leading.
x-height – Lower case alphabet as reference, x-height is the distance from baseline to the top of a lower case alphabet ‘x’.
For the purpose of estimation of no. of pages for a handwritten manuscript approximate values are given below for a few extensively used typefaces
Type face Column Measure Character per line
Arial 30 em 64
Times 27 em 66
Helvetica 30 em 63
Types of fonts
Serif fonts – Serifs form the sharp ends of the strokes of a typeface such as Times, Garamond. The figure depicts the style of the typeface.
Sans-Serif fonts – Typefaces which do not have any sharp strokes such as Helvetica, Arial, the figure below depicts the style of the typeface.
Monospace fonts – Fonts wherein the types occupy same horizontal width (body width) for all characters, best example is Courier.
Cursive fonts – Typefaces that takes decorative forms are classified as cursive fonts for example Zapf Chancery
Measure of Layout – Measure is the width of the text matter in a page, can also be defined by column width of text in a page.
Depth of Layout - Total no. of lines in a page constitute the depth of layout i.e. the vertical measurement of the text area excluding the margins.
Paragraph Alignments
Left Aligned – The text matter of a paragraph is aligned on the left side with respect to the page/column
Right Aligned - The text matter of a paragraph is aligned on the right side with respect to the page/column
Justified – The text matter of a paragraph is aligned on both side with respect to the page/column
Centered – The text matter of a paragraph is aligned on the center with respect to the page/column as shown in the pix below
In addition to the above styles of justification matter (specific cases of mathematical data) in a column can also aligned using comma or decimal
RECTO & VERSO pages
In printing and layouting terminology Recto signifies right side page and Verso signifies left side page depending direction of the script written, for example script written from left to right the recto page is the right hand side page and verso page is the left hand side page on the contrary for scripts written from right to left the Recto page is left hand side page and verso page is right hand side page
