Photoplotter

 

FP

8000/8000

 

XL

 

is

 

a

 

small,

 

raster,

 

low

 

cost

 

plotter

 

which

 

draws

 

image

 

on

 

film

 

by

 

means

 

of

 

laser

 

diode

 

light.

 

Film

 

itself

 

is

 

fixed

 

to

 

the

 

outer

 

surface

 

of

 

rotating

 

drum

 

by

 

means

 

of

 

masking

 

tape.

 

The

 

source

 

of

 

laser

 

diode

 

light

 

moves

 

step

 

by

 

step

 

along

 

the

 

rotating

 

drum.

 

Photoplotter

 

is

 

controlled

 

by

 

software

 

installed

 

on

 

PC

 

attached

 

via

 

its

 

USB

 

port

 

(PC

 

is

 

not

 

a

 

part

 

of

 

the

 

photoplotter

 

supply).

 

An

 

external,

 

universal

 

power

 

unit

 

is

 

used

 

to

 

supply

 

needed

 

power

 

(100

240V

 

AC

 

/

 

36V

 

DC

 

 

1.66A).

  

The

 

photoplotter

 

software

 

allows

 

to

 

read

 

input

 

files,

 

to

 

set

 

output

 

resolution

 

and

 

type

 

of

 

image

 

(negative,

 

mirror,

 

etc.)

 

drawn

 

on

 

the

 

film.

 

When

 

working

 

with

 

Gerber

 

files,

 

it

 

is

 

possible

 

to

 

check

 

and

 

modify

 

used

 

apertures

 

(D

codes)

 

and

 

make

 

simple

 

film

 

panelisation

 

for

 

Gerber

 

data

 

and

 

associated

 

drill

 

data.

 

Viewing

 

of

 

Gerber

 

files

 

and

 

conversion

 

of

 

various

 

types

 

of

 

aperture

 

files

 

is

 

possible

 

in

 

freeware

 

program

 

ViewMate

 

(made

 

by

 

Pentalogix,

 

formerly

 

Lavenir),

 

which

 

is

 

attached

 

to

 

the

 

photoplotter

 

software

 

for

 

your

 

convenience

 

(otherwise

 

it

 

may

 

be

 

downloaded

 

from

 

Pentalogix

 

web

 

page:

 

http://www.pentalogix.com/Download/download.html

).

  

Photoplotter

 

is

 

driven

 

by

 

program

 

Run_photo_USB

,

 

which

 

reads

 

in

 

hi

resolution

 

bitmap

 

files

 

FPF

,

 

(photoplotter

 

proprietary

 

file

 

format)

 

and

 

BMP

.

 

From

 

this

 

reason,

 

if

 

you

 

work

 

with

 

Gerber

 

or

 

Postscript

 

files,

 

these

 

files

 

must

 

be

 

converted

 

into

 

one

 

of

 

these

 

bitmap

 

files

 

format

 

first.

 

Gerber

 

files

 

are

 

converted

 

by

 

program

 

Gerb2bitmap

,

 

which

 

is

 

a

 

part

 

of

 

the

 

photoplotter

 

software,

 

while

 

Postscript

 

files

 

are

 

converted

 

by

 

an

 

external

 

program

,

 

supplied

 

as

 

an

 

option.

 

Converter

 

of

 

Gerber

 

files

 

has

 

also

 

built

in

 

converter

 

of

 

aperture

 

files

 

to

 

convert

 

various

 

aperture

 

format

 

into

 

one

 

standard

 

format

 

(Lavenir

 

format

 

is

 

used

 

as

 

a

 

standard

 

aperture

 

format).

 

Aperture

 

file

 

conversion

 

is

 

needed

 

only

 

when

 

working

 

with

 

standard

 

Gerber

 

format

 

RS

274

D

.

 

There

 

is

 

no

 

need

 

to

 

convert

 

aperture

 

file

 

when

 

working

 

with

 

extended

 

Gerber

 

format

 

RS

274

X,

 

as

 

this

 

type

 

of

 

file

 

already

 

contains

 

information

 

on

 

used

 

apertures.

  

Various

 

types

 

of

 

films

 

may

 

be

 

used

 

for

 

this

 

photoplotter,

 

but

 

all

 

of

 

them

 

must

 

be

 

sensitive

 

to

 

light

 

wave

 

length

 

of

 

670

 

nm

 

(red

 

light)

.

 

Thin

 

films

 

(0.1

 

mm)

 

used

 

by

 

image

 

setting

 

machines

 

as

 

well

 

as

 

standard

 

photoplotter

 

films

 

(0.18

 

mm)

 

can

 

be

 

used,

 

although

 

0.1mm

 

films

 

are

 

recommended

 

for

 

this

 

model

 

of

 

the

 

photoplotter.

 

Films

 

0.1mm

 

come

 

either

 

in

 

rolls

 

of

 

various

 

width

 

and

 

length,

 

or

 

in

 

pre

cut

 

sheets

 

of

 

several

 

sizes.

 

Film

 

in

 

roll

 

is

 

easy

 

to

 

tape

 

on

 

a

 

small

 

drum

 

in

 

photoplotter,

 

as

 

film

 

tends

 

to

 

bend

 

automatically.

 

There

 

are

 

several

 

manufacturers

 

of

 

suitable

 

films,

 

like

 

Kodak,

 

Horsell,

 

Fuji,

 

Agfa,

 

Typon

 

Graphic

 

Systems,

 

etc.,

 

while

 

films

 

have

 

various

 

names

 

like

 

EZR4,

 

RD4,

 

TR

LR+

.

 

As

 

film

 

light

 

sensitivity

 

differs

 

with

 

various

 

films,

 

several

 

test

 

plots

 

may

 

be

 

needed

 

to

 

find

 

suitable

 

light

 

intensity.

 

Films

 

have

 

to

 

be

 

wet

 

processed

 

(developed

 

and

 

stabilised)

 

like

 

any

 

other

 

films

 

after

 

lighted

 

in

 

photoplotter.

 

Film

 

manufacturers

 

recommend

 

and

 

usually

 

supply

 

chemicals

 

to

 

be

 

used

 

for

 

their

 

films

 

processing.
