![]() ![]() When fibers run parallel to the width of a sheet, the paper is grain short. When fibers are patterned parallel to the length of a sheet, the paper is grain long. Paper grain is either grain long or grain short. The grain of paper describes the direction, or alignment, of its component fibers. Opacity increases with the bulk and weight of paper, and is influenced by numerous other factors, including paper color, ink color, coatings, chemicals and coverage. High opacity, or density, minimizes the visibility of printing on subsequent pages, thus enhancing readability. The opacity of paper is the degree to which other printing is visible through the page. Brightness is important because it affects readability - high brightness can cause eye strain, while low brightness can produce a blurring effect. Unlike the color characteristic (which is highly subjective and imprecise), brightness is a strictly quantitative, or measurable, attribute. Remember: brightness and color are not the same thing. ![]() Most papers reflect approximately 60 to 90% of incoming light. The brightness of paper measures the percentage of light that it reflects.

White is by far the most popular color and is generally optimal for conventional usage. The color of paper is perhaps the most salient of all characteristics. Why does surface matter? Because people do judge books by their cover. As the extent of this process increases, paper is made smoother, glossier, more capable of retaining ink, thinner, less opaque and less bright. Calendaring affects paper in numerous ways. When paper is pressed at the mill, it passes through a series of rollers in a process called calendaring. The surface of paper affects its look, feel and printability. Paper has ten characteristics that affect its cost and appropriateness for a given job. Before you order though, you’ve got to know the menu. To the educated consumer, the choices don’t seem nearly as intimidating. Asking your printer for “white” is like asking your waiter for “food” - you’ll have to be more specific than that.
