Upload your image with text and select your print specifications to check whether the text is likely to remain readable after lenticular printing. The tool will flag potentially problematic text and provide recommendations when needed. This is meant to be a guide. Read Instructions here
This tool helps estimate whether text in your image will remain readable after lenticular printing. Using a trained AI model, we detect text within your image, measure its size and stroke width, and compare those measurements against the physical characteristics of the lenticular lens you select. This allows us to identify text that may become difficult to read after printing.
Choose the final size of your lenticular print. The readability of text depends heavily on the final printed dimensions, so be sure to select the size that matches your intended order.
Choose whether your image will be printed in Portrait or Landscape orientation. This ensures the analysis uses the correct physical dimensions when evaluating text size.
Choose whether your image will be printed as a 2-Flip or 3-Flip lenticular. Additional flips reduce the amount of image information available to each frame and can affect text readability.
For your first analysis, we recommend using Auto mode.
Auto Mode
Tests your image against multiple lenticular lens pitches.
Helps determine which lenticular sheets may produce the best text readability.
Provides a quick comparison of the available options.
Specific LPI Modes
After reviewing the Auto results, select a specific LPI to receive more detailed information about the text detected in your image and which text elements may be at risk.
LPI (Lines Per Inch) describes the number of lenticules in one inch of the lens material.
40 LPI – Largest lenticules, least image resolution, generally the least ghosting.
50 LPI – Higher resolution than 40 LPI, but will exhibit more ghosting.
75 LPI – Highest resolution of the available options, but also typically the most susceptible to ghosting.
Upload the image you intend to print. For best results, use the original high-resolution image whenever possible. Screenshots, thumbnails, or heavily compressed images may reduce analysis accuracy.
The AI model analyzes the text in your image and evaluates multiple factors, including:
Detected text size
Character height
Text stroke width
Lenticule width of the selected lens
One of the most important measurements is the relationship between the stroke width of the text and the width of the lenticule. If the strokes are too small relative to the lenticule size, the text may become difficult to read after printing.
The tool will classify the results as:
Good – The detected text should reproduce clearly.
Borderline – Some smaller text may become difficult to read.
Too Small – One or more text elements are likely too small for reliable readability.
When appropriate, the tool will also provide recommendations to help improve readability.
This Lenticular Text Readability Checker is a proprietary technology developed by 3DReactions specifically for lenticular printing. To our knowledge, no other online tool currently simulates text readability for lenticular prints in this way.
This tool is currently provided as a beta feature and should be used as a guide rather than a guarantee of final print readability. While our AI model has been trained to detect text, measure character size and stroke width, and compare those measurements against the physical characteristics of lenticular lenses, real-world results can vary based on image quality, font style, text color, contrast, viewing distance, printing conditions, and other factors. The analysis is intended to help identify potential readability concerns before printing, but it may occasionally classify text differently than what is ultimately observed in a finished lenticular print. We recommend using the results as a helpful reference when designing your image, particularly when working with small or important text elements.
