The Beta Video Ruler allows precise, non-contact measurements of large and small distances on Films, Plates, Dies, and Prints.
Small features are measured directly on the monitor by dragging the cursor across them. Large distances are measured by marking the starting point with the auto-snap cursor on screen. The camera and scale encoder are then moved to the opposite end of object. The cursor is then moved to within auto-snap distance and the total length is calculated and displayed on screen. This high-precision length gauge makes it possible to easily and accurately measure distances between marks with no physical edge to engage a caliper or micrometer.
The unique Video Color Separation system adds an extremely useful function when measurements are needed of process or spot color images, particularly when pastel colors or low-contrast images are involved. The process yellow image is nearly impossible to see against white paper even under magnification. Utilizing the adjustable separation system the color of interest is separated from the background and other interfering colors. It is converted to grayscale and displayed in real-time on the monitor while using the measuring functions. Offset, flexo, and screenprint registration marks are now easy to see and measure. Inkjet defects such as scatter, comets, and clumping are now easily imaged and measured.
Analyze and adjust film- and image-setter geometry over distances at large as 80 inches (2000mm). With an 80 inch scale you can measure the height, width, and diagonals of a 56.5 inch test square with a resolution of .001 inches. Calibrate large format plotter and printer output to qualify them for template production.
- Field of View: .345 " x .220" (8.75mm x 5.5mm)
- Resolution: 0.001" (0.01mm)
- Variable Illumination
- Automatic Exposure
- Image and Data Capture and Export
All Video Rulers offer the same magnification and software functionality.
The accuracy of the ruler is dependent upon the range of the device as shown below:
|16 inch / 400 mm
|24 inch / 600 mm
|30 inch / 750 mm
|40 inch / 1000 mm
|60 inch / 1500 mm
|80 inch / 2000 mm
A class certificate of an average instrument measurement are as noted in the above table.
If a Certificate of Calibration is required, it will be done by an accredited metrology laboratory and there is some delay because of shipping, scheduling, etc.
The cost is approximately $400. Needs to be specified when ordered.
PC & Video Interface Increases Functionality
Adds Data/Image Capture, Video Micrometer, & CMYK / Spot Color Contrast
Image enhancement to more easily see, capture and record all information
Benefits of the Video Ruler:
- Automatic edge detection and "snap", greatly minimizing operator error and variability
- Automatic data collection with labeling and formatting options
- Image capture and save with optional contrast enhancement and false-coloring
- Verifying film lengths before making plates
- Verifying plate lengths before mounting on cylinders
- Verifying proofs
- Analyzing registration variation
- Bar-code width checks
The camera added to the ruler’s digital readout makes targeting a snap. Being able to see a 1/2 inch (12 mm) image means you only need to positionthe ruler head to somewhere in the image, then use the on-screen cursor to easily and accurately position to better than 0.1mm.

Innovative Features - Move the cursor easily over the magnified image, rather than moving the entire optical system. Shadow-free illumination is provided by the LED and light guide system. Process and Spot Color enhancement/separation provide for improved contrast and visibility.
Small Details - Measure the height and width of objects that fit entirely within the field of view by clicking on the corner and dragging a line to the diagonally opposite corner. The x and y dimensions appear in the Local display.
Large Objects - Place the cursor and click at the start with the Set Zero Reference. Slide the digital encoder over the width of the object and place the cursor at the end point to calculate the length in the Global display.
Low Contrast - Enhance the contrast and visibility of process and spot colors by using the Separation feature. This yellow pattern is nearly impossible to see.
High Contrast - The image is electronically color enhanced to make the original pattern visible and eliminate the visual interference.
