13.1 Lighting Systems for Direct Part Marking
13.1.1 Lighting Systems for DPM Overview
ABR 7000 with red integrated illuminators are an optimum solution for all applications where codes are printed on paper
and for most applications where direct part marking is obtained by ink jet or laser etching technology on flat non-reflective
surfaces, without any evident machining flaws made by machine tools (that is, cutters or lathes).
When codes are marked on very reflective surfaces, the above illuminators can be used only if the reader's pitch or skew
angle required to avoid direct reflection doesn't compromise code reading due to perspective distortion of which the code
images are inevitably affected.
In other cases, where the above mentioned illuminators do not permit code image acquisition of
sufficient quality for
decoding, it is necessary to select a different lighting system for the ABR reader among those specifically designed for
Direct Part Marking (DPM) code reading applications.
13.1.2 Internal DPM Illuminators
Use ABR 7000 models with red integrated illuminators for:
• Applications where codes are printed on paper
• Applications where direct part marking is obtained by ink jet or laser etching technology on flat non-reflective
surfaces, without any evident machining
flaws
ABR 7000 models with Multicolored DPM integrated illuminators provide:
• Bright Field illumination for DPM code marking on flat surfaces having evident machining
flaws produced by
machining tools
• Dark Field illumination for DPM laser etching or dot peening code marking on
flat, highly reflective surfaces
13.1.3 Lighting Systems for DPM Selection Criteria
Lighting systems are designed for use in specific applications. The principle factors that determine selection of the most
suitable lighting system for a code reading application are:
