To complete the unit requirements safely and effectively, the individual must:
identify FOUR different substrate groups and suggest correct ink type for each groupexplain THREE possible sub-groups of plastic in relation to ink selectionexplain how to adjust process colour inks for correct colour balancedescribe TWO methods of improving opacity of a light coloured ink on a dark substrateoutline how to determine correct pad shape for the FOUR applications explain the effect that pad shape and hardness have on print qualitydescribe the effect commonly seen at the contact point of the nipple of a pad in a large solid print and how can it be avoidedoutline how to prepare a new pad before its first printingdescribe the correct plate type for these (given) applicationsexplain the difference between steel and photopolymer plates for process printingdiscuss reasons for mis-registered images, and how they can be correctedlist work health and safety (WHS) concerns of setting presses and doctor bladesdiscuss possible machine adjustments so the doctor blade operates correctlydescribe the effect of a damaged doctor bladelist various types of doctor blades and explain their applicationslist WHS concerns when using pre- and post-treating substratesoutline common pre- and post-treatment methods for different substratesexplain the importance of pre- and post-treatments for different substrateslist causes and solutions for SIX common print problems (eg hairlines around image, loss of density in the centre of a solid image, fine lines of ink running through image, distortion of image, picking up ink from substrate by subsequent pads, washed out images, loss of fine lines in images, inconsistent colour)identify where machine manuals, safety and other documentation relevant to this task are kept, and describe the information in them.
