If you have a halftone document, please skip to Question 16.

11. Describe the smallest significant detail and its location in your document:

____________________________________________________________________ ____________________________________________________________________

A significant detail is the smallest complete part of a document that is considered essential to the document's meaning. For textual materials, it is usually gauged against the smallest lower case 'e'. For non-textual materials, examples of significant details include an eye of a man in a portrait, a single pearl in a woman's necklace, a small bird in the background of a painting, or contour lines in a map. Hint: Find a very sharp and crisp detail rather than one that is fuzzy or not as well defined.

12. What is the color of the detail?____________________________________

13. Significant detail height (in millimeters to the nearest 1/10 mm): ____________

To measure the significant detail, use an eye lupe [1] or a microscope
that can distinguish detail as small as 0.1 mm.

14. Describe the finest stroke width and its location in your document:

____________________________________________________________________ ____________________________________________________________________

Examples: A fine line in a document, such as the thinnest line width used to render a letter in a manuscript, the thickness of a telephone line in a photograph, fringes of a hat in a sketch, etc.

15. Stroke width (in millimeters to the nearest 1/10 mm): ____________

To measure the significant detail, use an eye lupe or a microscope
that can distinguish detail as small as 0.1 mm.

16. Describe the selected document dimension (in inches):


A selected document dimension is the width of a section of your document, such as the distance between the roof of a house and a street sign in a photograph, or the length of a line of text in a letter. This dimension will be used to correlate pixels to inches so as to determine the effective resolution (DPI) of the digital image. Avoid selecting a measurement near the edge of the document.

17. Selected document dimension (in inches to the nearest 1/16"):______________


18. Color Information (please check one):

o Black and white [2]

Manuscript: Hand produced text, line drawings, blue prints, maps, etc.
Halftone or halftone-like: Regularly spaced pattern of dots or lines, often placed at an angle. Includes graphic art that is created using a fine and highly regular pattern of lines or hatchmarks, such as line engravings, etchings, etc.
Continuous tone or continuous tone-like: Smoothly varying gradation of tones. Includes photographs and some original art work, such as charcoal sketches, watercolors as well as graphic art, such as aquatints, lithographs, collotypes, etc.
Mixed: Contains both text/line art and continuous tone or half-tone. Includes newspapers, magazines, illustrated books, etc.
