TampaRotaSpeed TPRS - Marabu Printing Inks

Technical Data Sheet
TampaRotaSpeed TPRS
By adding Opaque Paste 170, the opacity of
colour shades can be significantly increased
without significantly influencing the chemical
or abrasion resistance. Maximum quantity to be
added is 15%. OP 170 is not suitable for adding
to white shades.
Printing Modifier ES contains silicone. It can be
used to rectify flow problems on critical
substrates by adding up to 1% by weight to the
ink. If an excessive amount is added, flow
problems are increased, and adhesion may be
reduced, especially when overprinting.
Cleaning
Printing pads
Pads in use have normally a hardness between
30-55 Shore A. If pad cylinders are self-cast, an
exact rotation must be guaranteed.
Printing machines
TampaRotaSpeed TPRS can be used for rotary
pad printing machines in inline-construction,
or for printing machines in satellite
constructions (“big wheel”). Depending on the
kind and use of the machine, the amount and
type of the used thinner must be readjusted.
For manual cleaning of containers, clichés, and
tools our cleaner UR 3 (flash point 42° C) or
UR 4 (flash point 52°C) can be used.
Clichés
In rotary pad printing with TPRS, good results
were achieved with a pad cylinder diameter of
100 mm or 200 mm. We recommend a cliché
depth of 22-30µm for a half tone cliché and
20-22µm for a non half tone cliché (open
etched).
With steel die plates, halftone films are used
with large images to avoid the doctor blade
falling into the etched area.
Doctor blade
Doctor blades of tempered steel are either
ground from both sides 0,5 mm or specially
ground from one side 0,3 mm.

Recommendation
The ink should be stirred well before printing.
To protect the ink in opened containers against
excessive drying, it can be carefully covered
with a layer of thinner which can then be later
stirred into the ink prior to printing.
Labelling
For our ink type TampaRotaSpeed TPRS and
its additives and auxiliaries, there are current
Material Safety Data Sheets available according
to EC-regulation 1907/2006 informing in
detail about all relevant safety data including
labelling according to the present EEC
regulations as to health and safety labelling
requirements. Such health and safety data may
also be derived from the respective label.
The ink has a flash point between 45° C and
55° C.
