 Installing HumanEyes Software- For the MAC OS 10.4 (Tiger)
- The installation is the same as for previous MAC versions except for the hasp, which requires the latest drivers from Aladdin. Without these drivers, the hasp will not be recognized by HumanEyes and you will not be able to run the software.
- You can download the drivers from Aladdin's website. Download and install the driver for OS X.4 (Tiger).
Using the HASP- The HASP Plug does not light up.
- If the red light in the HASP plug does not light up after connecting the HASP plug to the USB, you should first install the HumanEyes software which will also install the drivers for the HASP plug.
- If, after installing the software, the red light still does not light up, you should download the latest drivers for the HASP from Aladdin's website. Then download and install the "HASP Device Driver" that corresponds to your operating system.
- No Hasp Plug Connected.
- If you see an error message such as the following: "No HASP plug connected, or the plug connected is not a valid HumanEyes HASP plug", you should try to connect the HASP key directly to the computer for example directly into the monitor USB port.
- When the Hasp key is connected through a USB hub, or the keyboard, it is sometimes not recognized by the computer.
Running the Software- I received the following error when running the software: "Error creating file: definitions"
- You should make sure that you are logged in as a user with administrative privileges.
3D Printing- Printer resolution and choosing a Lens
- The printing resolution and the pitch affect the number of views that can be placed under each lenticule of a specific lens. The higher the lens's pitch, the higher the printing resolution required for effective 3D viewing.
- Size of lenticular pictures with HumanEyes
- Lenticular pictures are limited by the lenticular sheet dimensions. The standard largest lenticular sheet manufactured today is 48"(122cm) in width and 96"(244cm) in height, but these can be tiled to form a larger picture.
- Effects of printer resolution on the quality of the lenticular picture
- The higher the printer resolution, the higher the quality of the printed 3d image, much like any kind of printing. With lenticular images, a higher printer resolution allows the creation of more views, which increases the 3D effect.
- Finding the exact pitch for a lens
- Using the HumanEyes 3D pitch test tool, you can determine the accurate pitch of the lens.
Lamination- Necessity of lamination
- Lamination is not always necessary. When the printing device is incapable of printing directly on the lens, there is also a possibility of printing on paper and then laminating the paper to the lens. This requires aligning the printed image with the lens, and maintaining the alignment while laminating.
- Lamination method for attaching the picture to the lenticular plastic
- It is recommended to use regular cold lamination, also available in hot lamination machines.
- Choosing an adhesive for lamination
- It is recommended to use clear double sided adhesive.
- Reusing the lenticular plastic
- Lenticular lenses can be reused when the interlaced picture is printed on a film that is attached to the lens in a removable way. Examples include a «cling» type film, a removable double-sided adhesive, or any other substrate that can be removed without damaging the lens.
- The distance of the printed picture from the lenticular lens, caused by the thickness of the adhesive or by the thickness of the removable film, should be added to the original thickness of the lens for determining its characteristics. A thinner lens may therefore be needed compared to direct printing on the lens.
- Advantages of using reusable plastic
- By reusing the lenticular lens, users of HumanEyes 3D can dramatically reduce costs, as one of the significant costs is the plastic.
- Aligning the picture with the lenticular
- HumanEyes 3D creates alignment marks around the image which are used to align the lenticular lens and the image. Vertical alignment ensures the image strips are parallel to the lenticules, while center alignment ensures the best viewing experience by eliminating the 'jump' in the image when viewing it from the center.
- Special training for learning lamination
- There is no need for special training. The cold lamination process is a standard one. However, the accuracy of the alignment must be maintained.
- Laminating a picture immediately after printing (when the picture is still warm)
- Changes in temperature affect the size of most materials. Therefore, it is recommended to wait until the printing media has cooled before alignment and lamination.
