Colormark II

The SMARTEYE® COLORMARK™ ll Registration Mark Sensors combine unique color perception ability with very high speed response. Many important features have been incorporated into the design to meet the increasing demand for precision registration control on today’s higher speed packaging machinery.  It provides extended operating ranges, enhanced background suppression and the elimination of saturation problems.

The specific task of a photoelectric registration mark detector is to respond to printed registration marks on packaging material as they pass through the sensor's light beam. The output of the sensor must switch when the mark arrives precisely in position for the control function to occur. The resolution of the exact location of each passing registration mark is keynote to ensure that the initiation of the electromechanical response triggered by the sensor is in synchronization with the arrival of the mark.

HIGH SPEED
The high speed (50 microseconds) response time of the SMARTEYE® COLORMARK™ II helps to ensure that the point of detection of the sensed mark will not shift as the velocity of the moving web varies from slow startup to maximum velocity.

HIGH COLOR PERCEPTION
Color perception is a must for detecting registration marks printed in a wide variety of colors. The SMARTEYE® COLORMARK™ II with different light sources detects the greatest variety of color of marks on a wide veriety of material.

LIGHT SOURCES
Select  a white LED light source to detect a veriety of marks.  Select red, green or blue LED light sources in applications where the white light source fails to perform; i.e., a blue LED light source is recommended to detect pale yellow marks on a white background. Consult selection guidelines to help in specifying the correct SMARTEYE® COLORMARK™ II to fit your sensing requirements.

EDR® Enhanced Dynamic Range
(Patent No. 5,621,205)
The EDR® circuit extends the dynamic operating range to provide unequaled performance at very bright light levels. Dynamic operating range has been extended 500X to eliminate the effects of background suppression which can cause reduced resolution. To avoid saturation and enhance background suppression, the EDR® circuit monitors the offset adjustment during setup to determine when the sensor’s operating level is approaching the sensor’s light level saturation point. Before saturation occurs, the EDR® circuit adjusts the sensor in such a unique manner so as to prevent hot spot glare effects and extends the overall dynamic range of the SMARTEYE® COLORMARK™ II sensor.

CONTRAST INDICATOR
The 10 LED CONTRAST INDICATOR displays a scaled reading of the level of light received between the mark on the material and the material. The greater the reading between the two states, the more stable and accurate the detection of the mark will be.

LIGHT SOURCE SELECTION

Blue Light Source
Useful for detecting translucent, transparent, plastic, or glass objects in the retroreflective mode when using the R4 optical block. Used as blue filter for color perception advantages, i.e. resolving yellow vs. white colored objects or printed registration marks.

White Light Source
(Broadband Color Spectrum)
The “White Light” LED light source promotes easy detection of the largest variety of color marks printed on the largest variety of colored web materials. By combining a white LED light source, our Contrast Indicator, and the one-push AUTOSET setup, you have a winning combination of high performance with an easy to use sensor.

 

Red (Visible) Light Source
Visible red LED light source recommended for sensing transparent/translucent objects. Outperforms infrared light in many moderate to low contrast applications. Also recommended for use with plastic fiberoptic light guides.

Green (Visible) Light Source
Recommended for use only in applications where the color green provides an obvious advantage. An example would be sensing a light colored red/pink object on a white background. Also has been used in film processing applications when red or infrared light can cause damage to sensitive film.

Application Setup Guide:

Registration Mark Sensing Using Fiberoptic Light Guides

Opaque Material (Non-Foil)

  1. Position the fiberoptic light guide to view material looking straight down (see Fig.1).
  2. Place background in view of fiberoptic light guide.
  3. Adjust “offset” as follows...
    • For dark mark on light background, adjust for a reading of “10” on the Contrast Indicator with the background in view.
    • For light mark on dark background, adjust for a reading of “1” on the Contrast Indicator with the background in view.
  4. Set light/dark switch in the position that turns the “mark” indicator off.
  5. Move mark into view. Note the new contrast reading. lf this reading has deviated from the initial reading by 4 to 5 bars or more, enough contrast exists for proper detection.

 
Foil Material

  1. Position fiberoptic light guide as follows:
    • For a black or dark mark on shiny foil, position light guide to view material looking straight down (see Fig. 1).
    • For white or light mark on shiny foil, position light guide to view material looking on a 45° angle (See Fig. 2).
  2. Place mark in view of fiberoptic light guide.
  3. Adjust “offset” as follows:
    • For black or dark mark on shiny foil, adjust for a reading of “1” when the black mark is in view.
    • For white or light mark on shiny foil, adjust for a reading of “10” when the white mark is in view.
  4. Set light/dark switch in the position that turns the mark indicator “ON” when the mark is in view.
  5. Move mark out of view. With the background in view, note the new contrast reading. lf this reading has deviated from the initial reading by 4 to 5 bars or more, enough contrast exists for proper detection.

 
Transparent Material

  1. Position fiberoptic light guide to view material looking straight down.
  2. Place background (transparent area) in view of fiberoptic light guide.
  3. Adjust “offset” for a reading of 9 or 10 on the Contrast Indicator.
  4. Set light/dark switch in the position that turns the mark indicator off.
  5. Move the mark into view. Note the new contrast reading. If this reading has decreased or deviated from the initial reading by 6 to 8 bars or more, enough contrast exists for proper detection.

 
Hints and Tips:

  1. False tripping or erratic operation is usually caused by excessive web flutter, wrinkles or variations in material back ground color or marks. Minor adjustments of the “offset” can help to eliminate erratic operation.
  2. If the surface of opaque (non-foil) material is extremely shiny, consider placing fiberoptic light guide into the 45° angle position (see Fig. 2). The position that results in the maximum contrast deviation as displayed on the Contrast Indicator will give the most reliable performance.
  3. A metal guide plate for the material to flow across provides several necessary advantages:
    • Helps to iron out wrinkles.
    • Helps to eliminate web flutter.
    • Provides shiny background when sensing marks on transparent material.
