Step One : Pre Press Production

Before the job can be printed , the document must be

converted to film and “plate”. In the case of Ho Stuff

!or"s #$press, film ne%atives are created from di%ital

files. Ima%es from the ne%atives are transfered to

printin% plates in much the same a& as photo%raphs

are developed. ' measured amount of the li%ht is

alloed to pass throu%h the film ne%atives to e$pose to

li%ht, a chemical reaction occurs that allos an in"(

receptive coatin% to be activated. )his results in thetransfer of the ima%e from the netive to the plate.

)here are different materials for plates, includin% paper

*hich produces a loer +ualit& product. )he best

plate material is alumunium, hich is more costl&.

#ach of the primar& colors-blac",c&an,ma%enta and

&ello-has a separated plate. #ven thou%h &ou seeman&, man& colours in the finished product, onl& these

four colour are used *&oull also hear this called the

four(color printin% process /its a little li"e the three(

color process used in television.

Pre Press is the term used in the printin% and publishin%

industries for the processes and procedures thet occur

beteen the creation of a print la&out and the final

printin%. )he prepress procedures includes the

manufacture of a printin% plate, ima%e carrier or form,

read& for mountin% on a printin% press, as ell as the

adjusment of ima%es and te$ts or the creation of a

hi%h(+ualit& print file. In toda&s prepress shop, the

form of deliver& from the customer is usuall& electronic,

either a P12 or application files created from suchpro%rams as Scribus, 'dobe In1esi%n or 3uar"4Press.



Pre Press Processes

5.)&pesettin% : involves the presentation of te$tual

material in %raphic form on paper or some other

medium. Before the advent of des"top publishin%.

)&pesettin% of printed material as produced in print

shops b& compositors or t&pesetters or"in% b& hand,

and later ith machines.

6.7op&(editin% : is the or" that an editor does toimprove the formattin%, st&le, and accurac& of a

manuscript. 7op& editin% is done prior to the or" of

proofreaders, ho handle documents before final

publication.

8.9ar"up : is an artificial lan%ua%e usin% a set of

annotations to the te$t that %ive instruction re%ardin%the structure of the te$t or ho it is to be displa&ed.

9ar"up lan%ua%es have been in use for centuries, and

in recent &ears have also been used computer

t&pesettin% and ord processin% s&stems.

.Proofin% : involves creatin% an accurate facsimile of

the artor" before be%innin% productions runs. )his

serves as a bond beteen the printer an their customerthat the final product meets an a%reed upon standard.

Proofs in %eneral can be done for all parts * ima%es,

illustration, te$ts, and colors of print product. In this

part, three t&pes of proofin% should be chec"ed and

printed out : the print / read& P12 files, the printers

proof and the imposition proof. Print / read& P12 files

should be made after the la&out usin% prefli%ht at the



printn% house. )he printers proof should be printed out

in hi%h resolution and chec"ed b& the customer. )he

imposition proof, hich is usuall& done b& the printers,

should also be printed out to chec" and adjust theprintin% press.

;.Proofreadin% : traditionall& means readin% a proof

cop& of a te$t n order to detect an correct an& errors.

9odern proofreadn% often re+uaires readin% cop& at

earlier sta%es as ell.

<.Screenin% : adjustment of a continous tone of ima%essuch as photo%raphs.

=.Imposition : the combination of man& pa%es into a

sin%le si%nature form.

>.Separation : specif&in% ima%es or te$t to be put on

plates appl&in% individual printin% media *in"s,

varnishes, etc to a common print.

?.9anufacturin% : the usa%e of different materials of

plates should meet the needs of printin% method.

@suall& rubber, plastic and aluminum are used for

plates as ell as film hich is the photomechanical

e$posure and processin% of li%ht / sensitive emulsion

on a printin% plate. 9anufacturin% of plates should be

ell planned and delivered beforehand. 'lso , the cost

should be calculated as ell.

5A.9anufacturin% of hi%h +ualit& : print P12 file, hich

is used for the final printin%.

55.Paper Select : choosin% a proper paper is also a ver&

important step in prepress. In most modern publishin%

environments, the tas"s related to connect %eneration



and refinement are carried aout separatel& from other

prepress tas", and are commonl& characteried as part

of %rapich desi%n. Some companies combine the roles

of %raphic desi%n and prepress production into des"toppublishin% usuall& called 1)

)he set of procedures used in an& particular prepress

environment is "non as a or"flos ver&, dependin%

on the printin% process *e.% letterpress, offset, di%ital

printin%, screen printin% , the final product *boo"s,nespapers, product pac"a%in% , and the

implementation of specific prepress technolo%ies. 2or

e$ample, it is not uncommon to use a computer and

ima%e / setter to %enerate film hich is then stripped

and used to e$posed the plate in a vacuum frame C this

or"flo is h&brid because separation and halftonin%

are carried out via di%ital processes hile the e$posureof the plate is an analo% one. )hat demonstrates that

the borders around the prepress are ver& fluid.

2urthermore / dependin% on the printin% method and

the print product elements of the prepress of %raphic

print production can differ from case to case. )his

circumstance re+uires a mana%ement of the or"flo.

It is necessar& to mana%e the responsibilit& for eachpart of the or"flo. )hat can mean that emplo&ees,

ho are actuall& responsible for other parts of the

production , &ou have to attend to parts of the

prepress.
