Lenticular Printing
How does lenticular printing work?

Lenticular printing is a multi-step process consisting of digitally interlacing multiple images into a single file. The interlaced file is printed and then laminated (or printed directly) onto a lenticular lens. Viewing of this interlaced file under a lenticular lens sheet allows the viewer to see the lenticular effect such as 3D or animation. The most challenging step in preparing a lenticular image lies in the generation of the different views needed to create the lenticular effect. HumanEyes software provides a full set of tools for the creation of many different lenticular effects. 

What is the total price for producing and printing lenticular and 3D images?

Lenticular images’ production prices depend on:

  • The project’s complexity - design and processing time
  • The project’s size
  • The type of lenses used for the project
  • The needed quantity and other variable parameters such as lens prices, printing cost and finishing requirements. 
HumanEyes Products
What is the difference between the HumanEyes Producer3D and HumanEyes Creative3D software packages?

HumanEyes Producer3D is an end-to-end lenticular workflow solution designed for printers. This package includes the HumanEyes Creative 3D module.

HumanEyes Creative3D is a suite of tools designed to allow creative professionals to create 3D and lenticular images which then will be produced by printers using the HumanEyes Producer3D package. Using HumanEyes Creative3D designers have full control over the creative process of a lenticular image but can not do any production.

HumanEyes Producer3D and HumanEyes Creative3D applications allow designers and printers to work hand in hand.

What kind of effects can I print with HumanEyes solutions?

HumanEyes solutions allow you to create and design amazing lenticular projects with embedded animated effects like 3D, Flip, motion, zoom and movement.

How do I update my Hasp?

A HASP update will be sent to you with instructions.

In order to use it, make sure your HASP is connected and the red light in it is on, and follow these three steps:

  1. Make sure you upgrade both HumanEyes Creative3D and/or HumanEyes Producer3D
  2. Unzip the attached file
  3. Double-click the unzipped file.

You should receive the message “Updated the HASP successfully”.

IMPORTANT! If you don’t receive the success message, contact support@humaneyes.com

How can I find my HASP ID number?
  • Launch HumanEyes
  • Select “About HumanEyes…” 
I’m getting an error message: “No hardware key connected, or the key connected is not a valid HumanEyes key."

You need to make sure that your HASP is connected and working.

When the HASP is connected, you’ll see the light turned on.

If you don't see a red light in the HASP, you need to download and install the newest HASP driver.

The HASP driver installer can be found at:

Choose the file "HDD_Installer_MacOSX.dmg" .

Please make sure you restart your computer after updating the driver.

After restarting your computer, open the HASP update and follow the installation instructions. 

During the launch of the application I got the following error message “An unexpected system configuration has been encountered (10064)”.

The reason this error message occurs is due to the fact that the computer is not in administrator status, while trying to install or run the HumanEyes software. Changing the account on the computer to administrator status or having permissions set as an administrator in the computer will solve the problem. 

What is the file size limit in HumanEyes Creative3D?

The maximum output file size in HumanEyes Creative3D is unlimited.
The maximum input file size in HumanEyes Creative3D is up to 7000x7000 pixels (at 2D-3D).
In the case of using other effects, there is a possibility for bigger files.

Note: You need to make sure that the hard disk has enough free space before working with such sizable files. 

The filling Holes in HumanEyes Creative3D does not work. Are there limitations? Is there a way to check how to correct it?

The filling Holes command will not work if no depth is applied.

Another way for filling Holes can be achieved by using the tool “select Area”.
Select (mark by “lassoing”) the area of the holes (that was created after adding depth to the layer).
The next step is simply to fill the selected area by Tools->Fill Hidden Holes 

Can I interlace using HumanEyes Creative3D?

HumanEyes Creative3D allows you to interlace your artwork to 40 lpi 5x7”size for proofing and demonstration purposes only. Note, Creative3D is not an interlace engine. For interlacing your artwork in the designated lpi and size, you need to use HumanEyes Producer3D. 

Can an *.ldoc file be opened in HumanEyes1.3?

HumanEyes 1.3 does not support *.ldoc files. 

Is it possible to have layers with opacity in HumanEyes Creative3D?

Yes, HumanEyes Creative3D supports Layered PSD/Tiff file with opacity.

Note that HumanEyes Creative3D does not support any layer style, mask, fill & adjustment, smart layer, text layer or blending mode.

Plane layers are accepted.

What is the recommended Perspex (plastic) thickness in a lens free job?

The Perspex (plastic) thickness that should be assigned depends on the effect you want to achieve.

Generally 3-5mm is better for 3D jobs of 20-40 lpi
0.5mm-2mm is better for flip jobs of 40-20 lpi

We recommend doing a small test to determine the right parameters. 

How should I choose which lenticular lenses to use?

Different thickness lenses are suitable for different applications and printing methods. In general, thick lenses are more suitable for printing large format, long viewing distance applications. Thin lenses are more suitable for small, handheld products. The type of lenticular effect is also relevant: narrow angle lenses are more suitable for 3D, while wide angle lenses are better for flip and animation effects.

What is the recommended viewing distance of lenticular lenses?

Each lens has its own viewing distance.
We recommend checking lens manufacturers’ specifications. 

Printing & Equipment
What kind of equipment/material do I need for printing lenticular projects?

Most printing techniques support lenticular printing. However, offset printing is more suitable for narrow format, short viewing distance applications, while wide-format printing better applies to long viewing distance, wide format projects.

Basic recommendations for printing setups:

For Litho printing:

  • Capability for printing on plastic: UV, hybrid, fast drying systems
  • FM Stochastic screening or AM screening with at least 300 LPI
  • Make sure your printing machine supports the thickness of the lens
  • A hard ‘’quick release’’ blanket is recommended
  • Additional 5th and 6th color units recommended (for white back printing)

For digital printing:

  • LFP Roll ink jet (600 dpi and higher)
  • Flatbed ink jet (300 dpi and higher)
  • Photographic printer (300 PPI and higher) 
What equipment do I need to do wide-format lenticular printing?

To print wide-format lenticular images with HumanEyes software, you need:

For printing with lenses:

  • Lenticular lenses
  • Photo quality paper
  • Wide format laminator (cold) and double sided clear adhesive film.
  • Plastic cutting solution - recommended.

For printing LensFree:

  • Glass or Acrylic (Plexiglas).

For printing directly on the lens:

  • Flatbed press with UV curable ink system 
What is the common lenticular printing workflow?

There are mainly two options:

A) Printing & laminating:
Print an interlaced image on a paper and then mount the interlaced image under the lenticular sheet. Align using the alignment and registration marks.
After aligning/centering, a lamination or adhesive procedure is required.

B) Printing directly on the lenticular sheet:
When printing directly on a lenticular sheet, rapid curing techniques need to be applied.

Offset UV print or Flatbed UV are most commonly used for lenticular printing. 

I’m printing lenticular using an offset press. What is the recommended screening?

A: The angles for printing in 62 lpi are:
1) Dot screen is 374 lpi

C =112.5
M = 37.5
Y = 82.5
K = 67.5

2) Screening option for printing in 75 lpi is:

C = 15º
M = 75º
Y= 90º (should not be parallel to lenticels)
K = 45º

It is highly recommended to check the screening on the plate itself (before printing) 

How can I find a lenticular printer who uses HumanEyes’ technology? What is the Creative MarketPlace?

In March 2007, HumanEyes introduced the web-based Creative MarketPlaceTM. This service enables users of HumanEyes Creative3D to quickly post their projects on-line, and then to get price and time quotes from HumanEyes Producer3D printers.

What kind of lamination machine is recommended for laminating a lenticular lens?

We recommend using a wide-format laminator (cold) and double-sided clear adhesive film.
