1 Years Warranty (Additional support period of 3 years)

The ISO Camera Resolution Chart conforms to the ISO-12233:2000 standard, "Photography-Electronic still picture cameras - Resolution measurements". Hyperbolic wedges for resolution evaluation range from 100 - 2000 lines per picture height. Other features include checker patterns, multiple slant-edge lines, a center-focus zone plate and framing marks for 1:1, 4:3, 3:2, and 16:9 aspect ratios.

Paper/ink type: Semi-gloss OR Matte. Matte paper/ink can be used to reduce reflected light, but is slightly less sharp than semi-gloss paper. Semi-gloss paper/ink is recommended for most applications.

Please Note

This chart does not conform to the updated ISO 12233:2014 standard. We recommend thePhotographic ISO 12233:2014 E-SFR chart for testing that does not specifically require the old chart.

FAQs About  ISO Test Charts

For a proper color evaluation, ensure cleanliness, use standardized observation conditions, eliminate stray light, and periodically change the lamps.


In industrial production and quality control, color consistency is one of the core elements determining product quality. Whether it is the metallic paint for automobile coating, the dyeing effect of textile fabrics, or the ink matching in packaging and printing, subtle color deviations may lead to cost waste or damage to brand image.

The LAB color space defines colors with a three-dimensional model:

  1. Lightness (L): It indicates the lightness or darkness of a color, ranging from 0 (pure black) to 100 (pure white).

  2. Hue and Saturation (a and b):

    • The a-axis represents the red-green tendency, with positive values leaning towards red and negative values leaning towards green;

    • The b-axis represents the yellow-blue tendency, with positive values leaning towards yellow and negative values leaning towards blue.

It is a globally recognized standard and supported by most modern color measurement equipment. Color is quantitatively analyzed by measuring Lab values with instruments.


Gloss level is the extent of reflectance of light on a surface. It measures the shininess or dullness of a finish, from flat or matte to high gloss. It is important in aesthetic, functional, and quality control applications.


The main instruments used to detect color are spectrophotometers and colorimeters (including photoelectric integrating colorimeters). 

Spectrophotometer: High-precision option. It analyzes the full visible light spectrum to measure color accurately. Suitable for complex scenarios like textured surfaces, special effect colors, or batch consistency checks in industries such as paint and coatings. 

Colorimeter (Photoelectric Integrating Colorimeter): Cost-effective and portable. It uses RGB filters to measure tristimulus values directly. Ideal for quick color difference detection in simple applications. Key Selection Tip Choose based on accuracy needs: use a spectrophotometer for high-precision color measurement, and a colorimeter for fast, basic color difference checks.

Gloss levels are usually of five types, namely, matte, eggshell, satin, semi-gloss, and high gloss. These categories are of rising levels of reflectivity of the surface and are utilized to characterize the completion of paints, coatings, and other substances.
