StencilPro™ Imaging Times and Experiments
Disclaimer: The following tests should be used as a guide only and an exposure sample made proir to commencing your StencilPro™ exposures.
The following controls have been applied to all exposures to ensure consistency in artwork & developing:
All exposures made using artwork printed onto transparency film
Magnet Exposure Frame used for all exposures
Film placed into Opaque Storage Container immediately after exposure time, for minimum of 10 minutes with the lid covered - this stops additional light against the film during developing.
All washup in water using EZIscreen Washout Brush in a room with no overhead light until after washup is completed.
Exposed outdoors in direct sunlight

| HiRes | 'Cool White' Fluro Lamp @ 25cm height | 11 minutes | great result | Excellent | |
| HiRes | 'Cool White' Fluro Lamp @ 25cm height | 13 minutes | Overexposed, some pinholes developed during brushing of emulsion (user error: not all emulsion removed during developing) | Acceptable | |
| Standard | 'Cool White' Fluro Lamp @ 25cm height | 7 Minutes | Excellent result | Excellent | |
| Standard | 'Cool White' Fluro Lamp @ 25cm height | 8 minutes | Slightly Overexposed | Very Good | |
| Standard | 'Cool White' Fluro Lamp @ 25cm height | 6 Minutes | Under Exposed. Design all came out, however parts of outer screen also washing out. | Acceptable |
Exposed indoors under 5000K 'Quad Phosphour' (UV filtered) fluro tubes, using Fluro Light Exposure Kit
| Film Type | Exposure | Exposure Time | Comments | View Picture | Result |
| HiRes | 5000K Fluro Lamp @ 40cm height | 12 minutes | Under exposed - screen washed out | Unusable | |
| HiRes | 5000K Fluro Lamp @ 40cm height | 21 minutes | 95% of ultra fine details & shading | Very Good | |
| HiRes | 5000K Fluro Lamp @ 40cm height | 23 minutes | 100% of ultra fine details & shading | Excellent |
Notes
Broadband spectrum light should be blue to UV - upper blue spectrum is best
Compact Fluro is OK, but small image area is cast from narrow lamp. 40cm away using 100W 6500K lamp required.
6500K daylight bulk 15" height @ 12mins (reccomendation by CB)
