Control kit, from the measuring and from the self make-up
for screenprinters of industrials, graphics and textiles.
1- HALFTONE TEST Basic.
Film designed to know the limits of traditional printed halftone.
Helps to quantify the different parameters determining the print quality
The incidences of : stenciling, fabrics, inks, dilution, printing speed,
squeegee and flood-bar blades (shore degree, inclination, speed, sharpeningÉ),
off-contact,É will be easily seen with the RASTER TEST.
The word "basic" is not pejorative, some prints need coarse dots (30
to 65/inch) (12 to 26/cm).
2- HALFTONE TEST Advanced.
Same description but for dot counts from 55 to 90 line/inch (22 to
3- HALFTONE TEST Expert.
To control halftones from 90 to 150 dot/inch (36 to 60/cm).
4- FM TEST Stochastic (or random)
Dito with stochastic dots from 60 to 120 microns.
5- DOT CALCULATOR (Haltone dots count.)
Accurate measurement of the number of lines in halftone , with a precision
of one line of dot from
40 to 350 line/inch (15 to 138/cm) and their angle.
This precision tool allows you to control the degree of moire with
the MOIRE STOP.
6- MESH CALCULATOR (Screens.)
Accurate measurement of the stretched fabric, with a precision of one
thread. This precision will also help you control the moire
40 to 180/ cm (101 to 460/ inch).
7- FONT TEST
To estimate the capacity for printing of negative and positive texts,
of different fonts and different bodies.
8- LINE TEST
To visualize the difficulty of printing negative or positive lines
Measurement of saw-teeth. To compare direct emulsions and capillary
9- MOIRE STOP
The most innovating tool. A new tool to control the moire.
The moire, this "virus" of screenprinting is now surrounded. Everything
3 methods for use:
1) Starting from your screen (real thread count), you know which screen
and which halftone rule work.
2) Starting from supplied films, you know which screen choose.
3) Printing the films samples, in one single squeegee stroke, you visualise
10- COLOR TEST
Re-usable photographic films to be used as test strip in the margin
of the printed image, and allow you to control the register, the densities,
the color superpositions, the dot gain and loss for each colour.
11- GARNAUD MULTI TEST
Regrouped under a reduced format, they are the most useful tools.
They allow the screen printer to rapidly quantify the parameters which
are decisive in order to produce a quality print.
12- MOIRE DEMO
To bring a better understanding of the moire problems as well as the
diverse partners of the graphic chain to catch the problem.
This small tool help the screenprinter justify his choices of the halftone
rule and angles in front of the color separator.
You can even see the influence of the thread diameter on the moire
with the "moire demo" 3.
13- ANGLE CALC.
A classical protractor to measure the angles of the halftone.
14- DOT TEST
5 types of halftones on the same film : round, elliptical, square,
line and stochastic halftones, to watch, together with other effects, the
jumps in the color graduation
15- FONT CALC.
Measurements of font types for a better dialogue with the color separator.
Ratio of enlargement to obtain the halftone rule you wish to print.
17- CONVERSION INCH/CM
In France, the color separation basic measurement is the number of
lines of dots per inch and for the fabrics, the number of threads per centimeter
(except for the metallic gauzes).
Other countries, even French speaking ones, do the opposite. This picture
allows the conversion.
18- COMPENSATOR TEST
The present "basic" version" allows the screenprinter to understand
the necessity to make some corrections on the films.
Each screenprinter will have to create his own compensation curves.
19- EUCLIDIAN TEST
To compare different halftone rules, Euclidian and traditional (an
explanation is provided).
20- EXPOSURE TEST
Extreme values to set accurately screen lightening (what is not on
the screen will not exist while printing).
21- MESH ANGLE CALCULATOR
To match the possible inclination of the fabric on the screen, but
also to match if the warp and weft threads are perpendicular.
22- VARIABLE REGISTER
At each step during proofing, you must note every parameters.
The following picture will help you note and correct the failures one
The products of Serilor¨ LOG are intuitive
and allow to directly visualize the options.
An instruction manual is provided along with the supplied films of
