Abstract: A portable colorimeter housing (100) has an upper portion (103) which is mounted on a lower portion (101) in a cantilever fashion and is adapted to receive sheets larger than the device for purposes of obtaining tri-stimulus color measurements. An adjustable paper guide (119) determines the distance that a sheet is inserted between upper (163) and lower (161) plates. A sheet to be measured inserted in the opening (109) will operate a micro switch (139) which activates a motor operative to advance the sheet between a motor driven drive wheel (135) in the lower plate (161) and an idler roller in the upper plate (171). Transmittance or reflectance measurements are taken by means of photodetector cells (242) including colorimetric filters. A user programmable processor performs pattern recognition and control functions.
