Substrates
For traffic sign use, substrates found to be most reliable and durable are properly prepared aluminum
sheets and extrusions. Users are urged to carefully evaluate all other substrates for adhesion and sign
durability. Other substrates that may be satisfactory for proper application of sheeting will have the
following characteristics:
?
?
?
?
?
?
?
?
Clean
Smooth
Flat
Rigid
Dimensionally stable
Weather resistant
Non-porous
High surface energy (passes water break test)
Refer to Information Folder 1.7 for surface preparation recommendations. Substrates with low surface
energy may require additional preparation such as flame treatment, mechanical abrasion or use of
adhesion promoters prior to sheeting application.
Engineer grade prismatic sheeting is designed primarily for applications to flat substrates. Any use
that requires a radius of curvature of less than five inches should also be supported by rivets or bolts.
Plastic substrates are not recommended where cold shock performance is required. Sign failures
caused by the substrate or improper surface preparation are not the responsibility of 3M.
Screen Processing
Cutting and Matching
Engineer grade prismatic sheeting may be screen processed into traffic signs before or after mounting
on a sign substrate, using 3M ? Process Colors Series 880I or Series 880N. Series 880I or 880N
process colors can be screened at 60 –100oF (16 –38oC) at relative humidity of 20 –50%. A PE 157
screen mesh with a fill pass is recommended. Refer to Information Folder 1.8 for details. Clear
coating is not required or recommended. Use of other process colors series is not recommended. Care
should be taken to avoid flexing series 3430 sheeting before and especially after screening to
eliminate the possibility of cracking from improper handling techniques.
For screenprinted areas on white sheeting when processed according to 3M recommendations, the
coefficients of retroreflection shall not be less than 70% of the value for the corresponding color in
Table A. The color chromaticity and luminance shall conform to Table B.
Engineer grade prismatic sheeting may be cut into letters and shapes of at least three inches in height
and stroke widths of at least one half inch. Smaller sizes are not recommended. Sealing cut edges of
Series 3430 sheeting is not required.
Plotter Cutting
Programmable knife cut (electronic cutting)
1.
2.
Flat bed plotters can either die cut or kiss cut and offer the most consistent and reliable
performance.
Friction fed plotter. Kiss cut only. Success has been achieved using plotters that have 600 grams
of down force and a 60o cutting blade. Additional drive wheels may need to be added to improve
tracking. An alternative procedure is to cut sheeting from the liner side. Blade force and knife
depth must be set to score but not cut through the topfilm. Break apart individual copy or apply
premask to retain spacing.
Other Cutting Methods
Engineer grade prismatic sheeting may be hand cut or die cut one sheet at a time, and band sawed or
guillotined in stacks. Cutting equipment such as guillotines and metal shears, which have pressure
plates on the sheeting when cutting, may damage the optics. Padding the pressure plate and easing it
down onto the sheets being cut will significantly reduce damage. Maximum stack height for cutting
series 3430 sheeting is one and a half inch or 50 sheets. Details on cutting can be found in Information
Folder 1.10.
