1	The Scanner Round-Up ! Professional Scanner Performance and Applications PMA 2002 Summary Phil Lippincott President Aztek (949)770-8787 Phil@aztek.com
2	What is the Scan to Print Process & Workflow ? Film RGB Computer RGB C-R / M-G / Y-B Density to Intensity back to Density
3	Optical Resolution of Media vs Scanners ? Maximum Optical Resolution in Microns of Grain of Scanners Sensors
4
5	So How Can You Measure Scanner Optical Resolving Power or “Resolution”? 1951 USAF Resolution Test Pattern
6	You Read The Chart By Observing Line Pair Separation or Lack Of It
7	Resolution In Line Pairs / mm
8	Visible Line Pairs / mm are the equivalent of True Optical Dots Per Inch
9	Optical Resolution of Scanners Matters a lot Misleading Resolution Specifications! Scanned & Specified at 3049 PPI vs 2400 PPI
10	The Effects of Optical Resolution to Scanning Quality and Spot size are Significant for example Negative Film Grain at 5 Micron 5000 PPI Optical)
11	Compare 15 Micron Spot Size to 5 at 5000 PPI
12	Also Compare WET versus DRY MOUNT Scanning (both at 5 Micron 5000 PPI )
13	Film Wet Mounting with Kami is fast, easy and clean !
14	The Physics of Film ! “S” Shaped Density Not Monitor Intensity
15	Scanner Density Target: Test & Calibration
16	After Scanning Open In Photoshop and Read the Info
17	Density Noise is Also Shown
18	Density Value Goes Up As Noise
19	AZTEK Premier Drum Scanner Consistent Full Density Is The Goal
20
21	Summary Comparison by Quality Classes
22	Class One dominated by Drum Scanners
23	Class Three Quality Ranking
24	Class Two dominated by Quality CCD s
25	A Method to Compare Scanner Value Price Performance
26	Summary We’ve Learned How Good Film Really Is. Most People Under Estimate Film! We’ve Learned How to Test and Compare Scanners on an Even Playing Field with Each Other and Film. It Hopefully Is Clear That a Scanner can be as good as the film. There is not a perfect scanner, some are more suitable for different applications than others.
