1. Quality : It is a subjective term relating to expectations of the customer on the print job given by him. The level of expectation may vary between the Customer and the Printer, but when some one says ‘I need Quality job’, he expects the finished job to be on par with internationally accepted standards in terms of print quality, appearance and neatly executed job. However there is no measurement to weigh the quality aspect except by comparing one job with another job provided they are of the same variety.
2. Quarto: Any sheet when folded twice, i.e lengthwise once, again another fold lengthwise in the folded Sheet will show ¼ of the original size. The said ¼ th size is called the Quarto. Supposing the sheet is folded twice in irregular manner as shown in the illustration, can each piece be called Quarto? No, unless all the four pieces have equal length and width, and are either rectangle or square in shape, they are not to be called Quarto. Again another question. If the sheet is folded twice dimensionally and cut, will each triangled sheet be called Quarto? No they will also be not called Quarto but they can be called Quarto tringled paper in non technical way which again is not a standard name. Much before the A and B sizes of papers were accepted as standard, the personal stationery like the Note Paper and Pads, Envelopes and Long Envelops used to be mentioned in the in the sizes of Post Quarto (9’’x7’’), Large Quarto ( 10’’x8’’) and so on for Note papers and Pads, Duke quarto (3¾’’ x 5¾’’) and Medium Quarto (4¾’’ x 5¾’’) and so on for Envelops.
3. Quotation: There are several meanings for the term Quotation in Printing. The first is the space filling metal material used for locking up the hand composed matter in a metal frame for letterpress printing. They are also called quads or Quadlets or quadrats. Quads are extra wide spaces in the form of thin metal whose height will be less than the type fonts. The thicknesses of the quads will be expressed in terms of multiples of 1 Em space, 2 Em, 3 Em and 4 Em space. Occasionally 5 Em space is also used. The word Em is one of the unit level measurement in hand composing.
The second meaning for the term Quotation is the rates expressed for executing a specific job. The quotation will include cost of all items like paper, materials etc which may be used in the work, labour charges, service charges etc. Some of the charges may be hidden charges.
The third meaning for quotation in printing is suffixed with the word ‘marks’, thus reading quotation marks. Quotation marks always come in pairs. The general rule is that one should remember to open a quotation and close it at the end of the quoted material. The Quotation marks are written as a pair of opening and closing marks (given in Red color) in a sentence as shown below.
4. Quoin : Spelt as coin is a small vise like locking device to tightly lock the composed matter in the metal frame surrounded by metals like Quotations, Furniture and special wooden furniture (Sticks). The frame with composed matter locked with Quoins will be loaded on the Letterpress machine and printed. The Quoin is actually placed beyond the composed matter and in between the spacing material called Furniture that hold the composed matter tight in the frame.
5. Quire —
This is a term generally used in the Stationery shops to indicate the
quantity of sheets. Students bound writing Note books are also sold in
terms of One Quire, two, three and four Quire note books. One Quire
measure unit is equal to 25 sheets. Even loose sheets are sold in
multiples of 25 sheets called Quires. However quantities beyond 100 in
numbers are mentioned like 100 sheets, 150 sheets, half ream (250), one
ream (500) and so on.
6. Quickset Inks: This
variety of Ink is one of the most important inks used in printing that
prevents Set Off and rapidly dries in delivery pile. Quickset inks are
used mainly for printing Coated and Enamel paper stocks, and used on
high speed presses. The Quickset inks generally dry by Absorption cum
Oxidation cum Polymerization process as they contain balanced Oil,
Solvent and Carrier vehicle ratio. Quickset Intaglio inks is another new
development in the Printing industry as they are extensively used by
the Bank Note and Currency printing Presses where the speed of the
machine will require rapid drying on delivery pile, retain their
relief on printed sheets, and do not cause set off problem. As modern
development Infra Red light devices are also used to speeden up the
drying process by the time the sheets are delivered on the delivery
7. Quality control :
In any industry, the Quality Control aspect plays a vital role. In
major Printing Presses the Quality Control is essential to execute the
work to the fullest satisfaction of the Customer. Quality Control
doesn’t start and end on printing machine alone. It needs to be
practiced right from the stage of procurement of material to the
finishing end activities for the product. In order to maintain the
quality control, certain standard trade practices are followed in each
and every processing zone . For example the quality of the negatives
made, quality of the plates made, the process and specific chemicals or
materials used in those areas, the type of paper and ink procured,
paper conditioning, cooling period for the printed stocks, the manner in
which they are handled and so on are closely monitored by the Quality
Control department by random checking. Random sampling checks to assess
the quality of the material used is also done.
8. Quarter tone:
This again relates to the formation of the halftone dot pattern. The
dot formation between the highlights and Middle tones are generally
referred to as Quarter Tone which will be 25% of the size of dots as
seen in the darkest area. The darkest areas in an image is called Shadows. The
lightest areas are called the Highlights. The rest of the areas in
between them are generally called Middle tones.
However when the Middle tone is also broadly split into two areas to
express the tonal values i.e between the middle tone and the High light
areas, the areas which have dots showing almost 25% value compared to
the dots in shadow areas or the mid value of dots in between the dots
in High light and the darkest Middle tone areas are called Quarter
This is a guide to the process operators who can accordingly improve the
imaging by giving four groups of dots to increase the clarity of the
image. To understand this see the model illustration.
