The program
The program consists of a central module levels. At these levels images and masks can be loaded, which determine the transparency of each underlying level. The masks are SW images, where white = opaque and black is transparent =. Grays care depending on their value for semi-transparent transitions. The background layer has no mask. The “X” button, individual layers on visible or invisible. The small red or green box shows at a glance, whether the relevant level pattern or 2D image is (red = Pattern).
The images at each level can be assigned to properties. A layer can pattern, so deep structure, or be used as a 2D bitmap. When a layer “Pattern is”, then it can be defined as pseudoscopically (forward out of the picture so kicking). Further, patterns can be masked on the shape of the lens (or not). The amount of increment determines the depth. Larger step sizes provide deeper images. but deeper images are also blurred, so that you – should not exceed reasonable extent – on a case-to-find.

There are no options, because the picture is full surface 2D ready at his level. The image to the charged mask determines the manner and degree of illumination.

The “Mask Pattern” option is enabled, the image is limited to lens size. The “Pseudoscopic” option would activate when this pattern should not be located in the depth behind, but in the space in front of the image plane. Below is the step size (and thus the depth) set. The red arrows cause a reload of the load at this level of the image or the mask.
The result is displayed.
Links below the preview, you can choose if a 3mm Beschnittmarkierung to display or not. This mark does not render the result. It is used only for your information.
Before you build your design, you must first make some basic settings. Enter the LPI value for the X and Y direction. Right of entry fields is a checkbox that is preconfigured with some common lenses. Select the LPI settings from this box if your material is offered there. Enter continue a print width and height in mm. Then select the resolution of your output device. Below, you can choose between different types of lenses. Quantum can create structures for all kinds of FlyEye-, integral and also for lenticular lenses. Once you have loaded the first image in one of the planes, these options are no longer available. You must make this setup so first.
If you want to make changes in the basic set-up, so as resize, then click the “New” button. All images are removed, the setup options are available again and can be changed. Then click on the button with the red arrow. The images of your design can be reloaded. This procedure is necessary because the values of the setup and the program’s internal preparation of images and their representation in the preview are interconnected.
Render the Output (TIF format) by clicking on “Create Output”. With “Open and Save Project” to save your design in order to access it at a later time again can.
If you activate the “Auto Print Output”, then after each rendering the result is sent to a printer. The first time you must select the printer and the quality and adjust. Subsequent prints go automatically if the option to the printer. “Print last” prints the last rendered image.
The button “Call Pitch test” calls the pitch test module, which allows you to determine the pitch value of FlyEye- and lenticular lenses with approximate accuracy.
Thats how it works:.
Make a lens piece of ca 5×5 cm size a scan with 1200 DPI resolution. You can do this with any flatbed scanner. Set behind the lens a piece of black cardboard to increase the contrast of the lens in the scan display. Then load the scan into the pitch test module.
The Pitch test module guides you in 6 steps. Step 5 is the actual measurement. The program prompts you to the red dot inside the center of a lens (or exactly in between) to put. Then make a regulator the black dots so that they are all in the center of the subsequent lens (or exactly between two adjacent lenses).
The result of this adjustment is the pitch of the lens for examination.
If you measure lenses in X and Y directions have different pitch values may, then you need to turn the scan for a second measurement at 90 degrees. Of course you can also measure normal lenticular lenses with this program. The precision of the measurement is approximately 0.2 LPI. It is therefore useful to refine the LPI value either with a printed test pitch or with a series of experiments. Please also note that the “optical Pitch” and the measured here “actual pitch” are different. This is due to the optical properties of the lens with respect to the viewing distance and at various prepress and printing costs. Here only geometric physical characteristics of the lens are measured.
