1) Nowadays what is screen printing mesh made from?
Choice 1 Polyester
Choice 2 Polyurethane
Choice 3 Silk
Choice 4 Nylon
Choice 1 Steel

 

2) Which of these images is likely to be printed using a stencil that is produced with liquid emulsion that has a face coat applied?

 

3) The unit measure of tension is:
Choice 1 RZ
Choice 2 Shore
Choice 3 Microns
Choice 4 Newtons

 

4) Which of the following statements is correct?
Choice 1 Tension has very little effect on the print
Choice 2 A high tension is best
Choice 3 The best way to check if mesh tension correct is by bouncing a coin on it

 

5) In this example what does 140/355-34Y PW signify in a mesh specification?
Choice 1 140 microns/0.355� mesh opening - 34 microns thread diameter � yellow mesh � plain weft
Choice 2 140 threads per centimetre/355 threads per inch - 34 micron thread diameter � yellow mesh � plain weave
Choice 3 140 microns/0.355� mesh thickness - 34 microns mesh opening � yellow mesh � plain weft

 

6) Accepting that most meshes now are plain weave, what are the main characteristics of mesh that affect the ink deposit?
Choice 1 Mesh Count
Choice 2 Thread Diameter
Choice 3 Mesh Thickness
Choice 4 Mesh Weight

 

7) What is the hidden energy of the process?
Choice 1 Squeegee movement
Choice 2 Ink flow
Choice 3 Mesh tension
Choice 4 Mesh opening

 

8) Liquid emulsions and capillary film are:
Choice 1 Direct emulsions
Choice 2 Indirect emulsions

 

9) What does EOM stand for?
Choice 1 Emulsion on mesh
Choice 2 Emulsion overt mesh
Choice 3 Emulsion outside mesh
Choice 4 Emulsion over mesh

 

10) In the printed example what are the likely causes of the loss of definition on the second R? (These have been printed off different stencils)


Choice 1 Underexposed emulsion
Choice 2 Over exposed emulsion
Choice 3 Poor contact of photopositive with emulsion

 

11) If an emulsion is not dried sufficiently, when it is exposed will it be?
Choice 1 Over exposed
Choice 2 Under exposed

 

12) What will you see in a developed stencil that has not been dried sufficiently ?
Choice 1 Pinholes
Choice 2 Fisheyes
Choice 3 Water stains
Choice 4 Dust particles

 

13) When coating the mesh wet on wet on what side should the last coat be made?
Choice 1 Squeegee side
Choice 2 Print side

 

14) What instrument is used to measure the roughness of the stencil?
Choice 1 Spectrophotometer
Choice 2 RZ meter
Choice 3 Magnifying glass

 

15) Why is it important to have as flat stencil as possible?
Choice 1 To stop ink seeping out of the mesh
Choice 2 To stop the squeegee juddering while printing
Choice 3 To give good edge definition

 

16) Is it better to have a?
Choice 1 High RZ reading
Choice 2 Low RZ reading

 

17) The reason for coating the print side of the stencil after it has been coated and dried is to?
Choice 1 Make a thicker stencil
Choice 2 Improve the RZ
Choice 3 Stop the emulsion from breaking down
Choice 4 Fill in any pinholes

 

18) If the image on a photopositive is 1000 mm and the humidity increases by 1% rh what will be the effect on the image size?
Choice 1 The image will increase in size
Choice 2 Rh has no effect on the photopositive
Choice 3 The image will decrease in size
Choice 4 It depends how long the stencil is exposed for

 

19) What instrument is used to check the dot area and the density of the emulsion on the photopositive?
Choice 1 Reflection densitometer
Choice 2 Transmission tensiometer
Choice 3 Transmission densitometer

 

20) When printing 4 colour process what is the acceptable difference in tension between all four stencils?
Choice 1 +/- 1 Newton
Choice 2 Varying tensions don't make any difference
Choice 3 3 Newtons
Choice 4 +/- 1 Shore

 

21) Which flood coater profile would you use for printing four colour process?
Choice 1
Choice 2
