In order to effectively utilize the entire range of available LPI in a halftone system, an image selected for printing generally must have 1.5 to 2 times as many samples per inch (SPI). For instance, if the target output device is capable of printing at 100 LPI, an optimal range for a source image would be 150 to 200 PI.
However, from December 1982 through December 2011, the all-items CPI-E rose at an annual average rate of 3.1 percent, compared with increases of 2.9 percent for both the CPI-U and CPI-W. [28] This suggests that the elderly have been losing purchasing power at the rate of roughly 0.2 (=3.1–2.9) percentage points per year.
Dots per inch (DPI, or dpi [1]) is a measure of spatial printing, video or image scanner dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch (2.54 cm).
For instance, at www.lexmark.com they tell that "resolution is measured in dpi (dots per inch) which is the number of pixels a device can fit into an inch of space." And at www.olympus-europa.com, they tell that a 640 x 480 pixels image at 150 dpi will end up as 10.84 x 8.13 cm in the print.
The Bureau of Labor Statistics released its November Consumer Price Index (CPI) at 8:30 a.m. ET on Tuesday. Here are the main figures from the report, compared to Wall Street estimates.

A CPI is a statistical estimate constructed using the prices of a sample of representative items whose prices are collected periodically. Sub-indices and sub-sub-indices can be computed for different categories and sub-categories of goods and services, which are combined to produce the overall index with weights reflecting their shares in the total of the consumer expenditures covered by the ...
In 1996, the Advisory Committee to Study the Consumer Price Index (the Boskin Commission) estimated that in 1996 CPI-W (used to adjust Social Security) over-estimated inflation 1.1 percent. The BLS responded by making changes to the CPI-U and CPI-W, which included an adjustment to compensate for upper-level substitution bias , performed each ...
