Inkjet Printing

Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. Inkjet printers are the most commonly used type of printer and range from small inexpensive consumer models to expensive professional machines. The concept of inkjet printing originated in the 20th century, and the technology was first extensively developed in the early 1950s.
While working at Canon in Japan, Ichiro Endo came up with the idea for a "Bubble jet" printer, while around the same time Jon Vaught at HP was developing a similar idea. In the late 1970s, inkjet printers that could reproduce digital images generated by computers were developed, mainly by Epson, Hewlett-Packard (HP) and Canon. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales Canon, HP, Epson, and Brother.
In 1982, Robert Howard came up with the idea to produce a small colour printing system that used piezos to spit drops of ink. He formed the company, R.H. (Robert Howard) Research (named Howtek, Inc. in Feb 1984) and developed the revolutionary technology that led to the Pixelmaster colour printer with solid ink using Thermojet technology.
This technology consists of a tubular single nozzle acoustical wave drop generator invented originally by Steven Zoltan in 1972 with a glass nozzle and improved by the Howtek inkjet engineer in 1984 with a Tefzel moulded nozzle to remove unwanted fluid frequencies. The emerging ink jet material deposition market also uses inkjet technologies, typically printheads using piezoelectric crystals, to deposit materials directly on substrates.
The technology has been extended and the 'ink' can now also comprise solder paste in PCB assembly, or living cells, for creating biosensors and for tissue engineering. Images produced on inkjet printers are sometimes sold under trade names such as Digigraph, Iris prints, giclée, and Cromalin. Inkjet-printed fine art reproductions are commonly sold under such trade names to imply a higher quality product and avoid association with everyday printing. Fluid surface tension naturally pulls a stream into droplets. Optimal drop sizes of 0.004 inch require an inkjet nozzle size of about 0.003 inches.
Fluids with surface tension may be water based, wax or oil based and even melted metal alloys. Most drops can be electrically charged. There are two main technologies in use in contemporary inkjet printers: continuous (CIJ) and drop-on-demand (DOD). Continuous inkjet means the flow is pressurised and in a continuous stream Drop-on-demand means the fluid is expelled from the jet nozzle one drop at a time. This can be done with a mechanical means with a push or some electrical method. A large electrical charge can pull drops out of a nozzle, sound waves can push fluid from a nozzle, or a chamber volume expansion can expel a drop. Continuous streaming was investigated first many years ago. Drop-on-demand was only discovered in the 1920s.

market...........”
Keywords: market, Canon
Keyword Location: para B, lines 3-4
Explanation: Para B discusses the major companies that dominate the inkjet printer market. This matches well with the heading "Establishments that rule the inkjet printer market. Hence I is the correct answer.

Paragraph C

Answer: IV
Supporting statement:“........In 1982, Robert Howard came up with the idea to produce a small colour printing system that used piezos to spit drops of ink. He formed the company, R.H. (Robert Howard) Research...........”
Keywords: printing, revolutionary
Keyword Location: para C, lines 1-2
Explanation: Para C tells Robert Howard's innovation in colour printing technology, which revolutionised the field. This fits the heading "A concept that transformed colour printing. Hence IV is correct.

Paragraph D

Answer: IX
Supporting statement:“........This technology consists of a tubular single nozzle acoustical wave drop generator invented originally by Steven Zoltan in 1972 with a glass nozzle and improved by the Howtek inkjet engineer
...........”
Keywords: nozzle, improved
Keyword Location: para D, lines 1-2
Explanation: Para D describes the advancements made to the nozzle technology to eliminate unwanted fluid frequencies. This aligns with the heading "A nozzle upgraded to eliminate undesirable fluid regularities

Paragraph E

Answer: II
Supporting statement:“.........Images produced on inkjet printers are sometimes sold under trade names such as Digigraph, Iris prints, giclée, and Cromalin. Inkjet-printed fine art reproductions are commonly sold..........”
Keywords: reproductions, higher
Keyword Location: para E, lines 3-4
Explanation: Para E explains how inkjet-printed images are marketed under specific trade names to denote higher quality, distinguishing them from routine printing. This fits the heading "Distinguishing routine printing with a better quality product.

Paragraph F

Answer: VII
Supporting statement:“........There are two main technologies in use in contemporary inkjet printers: continuous (CIJ) and drop-on-demand...........”
Keywords: demand, fluid
Keyword Location: para F, lines 3-4
Explanation: Para F describes the different methods used to expel fluid from the nozzle in inkjet printers, focusing on continuous and drop-on-demand technologies. Hence the heading "Different ways of dipping fluid from the nozzle” is correct.
