  • Page 8: Safety

    • Ultra Dottie II may not be used in an area with strong electromagnetic fields. • Use the Ultra Dottie II in ambient temperatures between 10°C (50°º F) and 40°C (104°F), and do not expose the Ultra Dottie II to direct sun light.

  • Page 9: Packaging And Transport

    • Use original Beta Industries spare parts and accessories only. • Use the original packaging exclusively when transporting the device. • The Ultra Dottie II case can be cleaned with a cloth moistened with soapy water 2.3 Packaging and transport Always transport Ultra Dottie II in the original device case to avoid damage.

    Dot size: 120µm The reference plate used by Beta Industries is an extremely precise glass substrate that is metal vaporized and, as is used in semiconductor manufacturing, etched out. It is embedded in gray plastic. The reference plate has a lifetime of two years. The expiration date and the serial number are printed on the label.

    3.4 Inputting a reference curve The user can switch to ‘Input a reference curve’ by selecting the function in the settings window (see section 3.3). You will find the toolbar on the left side of the LCD. An XY diagram of the defined sample points for the current reference curve is shown on the LCD.
  • Page 22 • The default value for this sample point corresponds to the nominal value. Now select the function to increment or to decrement and press the <ENTER> button. If the reference curve is altered at least once, the Ultra Dottie II will create a sample point for the reference 21/40...

  • Page 24 The visual coverage is a ‘density’ measurement, which is not compatible with any current standard and can only be used for comparative analysis. For density measurement, we recommend using a Beta Industries densitometer conforming to standards. Only the dot area is usually determined in stochastic screens. However,...

  • Page 25: Calibration

    Please use the Vip Target to check the accuracy of the device (see chapter 2.5.2). As the Ultra Dottie II calibration is done automatically, no calibration or “zeroing” on the plate is needed. After inputting the appropriate settings...

  • Page 26: Measuring Standard Plates

    This zeroing is done by a measurement on the medium (e.g. plate ground). To check the absolute accuracy of the Ultra Dottie II, Beta Industries offers the Ultra Dottie II Target. With the help of this tool, the device can be checked and calibrated (see section 2.5.2).

  • Page 27: Measuring Film

    For measurements on black, the color (K) must always be selected manually. The Ultra Dottie II is equipped with a video camera, which measures the geometric dot size, relevant for plate readings. For prints, the densitometric dot size needs to be measured, as this measurement corresponds to the visual impression.

  • Page 28: Measurement Values

    3.5.7 Measurement Values 3.5.7.1 Dot area This value represents the area coverage of the measured patch. With the image analysis algorithm, dust and image errors are eliminated. 3.5.7.2 Screen ruling Depending on the settings, the screen ruling is displayed either in Lines/inch or Lines/cm.
  • Page 29 Hold the Ultra Dottie II parallel to the edge of the plate to get a correct value of the screen angle in degrees. Important: The screen angle is not shown for FM screening and for middle tones, especially for chain dots in AM screening. In a regular screen, the screen angle will always be shown if the dot area has closed dots (highlights and shadows).

  • Page 30: Visually Checking The Dot

    3.6 Visually checking the dot After a measurement the picture will be held in the device’s memory until the next measurement and can be displayed or transferred to a host computer at any time by selecting the function As usual you will find the toolbar on the left side of the LCD with the following functions.

  • Page 31: Measuring A Plate Characteristic Curve

    Transferring the binary image to a host makes it possible to document the dot quality. As an option Beta Industries offers the BetaTab software, which can accept the binary image and copy it into any application that supports the clipboard.
  • Page 32 The following information is shown in the LCD: • Reference curve: this is drawn in light gray. The sample points (patches being measured) are indicated by vertical lines at the corresponding locations. • Plate characteristic curve: this is drawn in black, with the curve being plotted accordingly after each measurement.
  • Page 33 • Select the function with the <UP> or <DOWN> button and execute this using the <ENTER> button. All reference values are reset. The nominal value 5% and the reference value 5% are shown. • Measure the 5% patch. The measured value is shown at the top edge of the Y axis and the 5% reference value is shown below it.
