Apply Adaptive sầu Compression


Divides each page inlớn black-and-trắng, grayscale, and color regions và chooses a representation that preserves appearance while highly compressing each type of nội dung. The recommended scanning resolutions are 300 dots per inch (dpi) for grayscale & RGB input đầu vào, or 600 dpi for black-and-White input đầu vào.


Color/Grayscale Scans


When scanning color or grayscale pages, select one of the following:


JPEG2000


Applies JPEG2000 compression to lớn the colored image nội dung. (This setting is not recommended when creating PDF/A files. Use JPEG instead.)


ZIPhường


Applies ZIPhường compression to the colored image nội dung.


JPEG


Applies JPEG compression khổng lồ the colored image content.


Note:

The scanner uses either the selected Color/Grayscale option or the selected Monochrome option. Which one is used depends on the settings you select in the Acrobat Scan dialog box or in the scanner’s TWAIN interface, which may open after you cliông chồng Scan in the Acrobat Scan dialog box. (By default, the scanner application dialog box does not open.)


Monochrome Scans


When scanning black-and-White or monotone images, select one of the following:


JBIG2 (Lossless) &JBIG2(Lossy)


Applies the JBIG2 compression method lớn black-and-white input đầu vào pages. Highest-quality levels use the lossless method; at lower settings, text is highly compressed. Text pages typically are 60% smaller than CCITT Group 4 compressed pages, but processing is slow. Compatible with Acrobat 5.0 (PDF 1.4) và later.


Note:

For compatibility with Acrobat 4.0, use a compression method other than JBIG2.


CCITT Group 4


Applies CCITT Group 4 compression lớn black-and-white input đầu vào page images. This fast, lossless compression method is compatible with Acrobat 3.0 (PDF 1.2) and later.


Small Size/High Quality


Sets the balance point between tệp tin kích cỡ & quality.


Deskew


Rotates any page that is not square with the sides of the scanner bed, to make the PDF page align vertically. Choose On or Off.


Background Removal


Whitens nearly Trắng areas of grayscale và color input đầu vào (not black-and-white input).


Note:

For best results, calibrate your scanner’s contrast & brightness settings so that a scan of a normal black-and-White page has dark gray or black text & a trắng background. Then, Off or Low should produce good results. If scanning off-White paper or newsprint, use Medium or High to clean up the page.


Descreen


Removes halftone dot structure, which can reduce JPEG compression, cause moire patterns, & make text difficult to recognize. Suitable for 200–400-dpi grayscale or RGB đầu vào or, for Adaptive sầu Compression, 400–600-dpi black-and-white input. The On setting (recommended) applies the filter for 300 dpi or higher grayscale và RGB đầu vào. Select Off when scanning a page with no pictures or filled areas, or when scanning at a resolution higher than the effective range.


Text Sharpening


Sharpens the text of the scanned PDF tệp tin. The default value is low và suitable for most documents. Increase it if the quality of the printed document is low and the text is unclear.

By default the OCR language is picked from default locale. To change the language, clichồng Edit and choose a different language.

Scanning tips

Acrobat scanning accepts images between 10 dpi & 3000 dpi. If you select Searchable Image or ClearScan for PDF Output đầu ra Style, input đầu vào resolution of 72 dpi or higher is required. Also, input đầu vào resolution higher than 600 dpi is downsampled to lớn 600 dpi or lower.

Lossless compressions can only be applied khổng lồ monochrome images. To apply lossless compression to a scanned image, select one of these options under the Optimization Options in the Optimize Scanned PDF dialog box: CCITT Group 4 or JBIG2 (Lossless) for monochrome images. If this image is appended to a PDF document, & you save sầu the tệp tin using the Save sầu option, the scanned image remains uncompressed. If you save the PDF using Save As, the scanned image may be compressed.

For most pages, black-and-white scanning at 300 dpi produces text best suited for conversion. At 150 dpi, OCR accuracy is slightly lower, and more font-recognition errors occur; at 400 dpi & higher resolution, processing slows, and compressed pages are bigger. If a page has many unrecognized words or small text (9 points or smaller), try scanning at a higher resolution. Scan in black and trắng whenever possible.

When Recognize Text Using OCR is disabled, full 10-to-3000 dpi resolution range may be used, but the recommended resolution is 72 và higher dpi. For Adaptive Compression, 300 dpi is recommended for grayscale or RGB input, or 600 dpi for black-and-Trắng input đầu vào.

Pages scanned in 24-bit color, 300 dpi, at 8-1/2–by-11 in. (21.59-by-27.94 cm) result in large images (25 MB) before compression. Your system may require 50 MB of virtual memory or more to scan the image. At 600 dpi, both scanning và processing typically are about four times slower than at 300 dpi.

Avoid dithering or halftone scanner settings. These settings can improve sầu the appearance of photographs, but they make it difficult lớn recognize text.

For text printed on colored paper, try increasing the brightness và contrast by about 10%. If your scanner has the color-filtering capability, consider using a filter or lamp that drops out the background color. Or if the text isn’t crisp or drops out, try adjusting scanner contrast & brightness to lớn clarify the scan.

If your scanner has a manual brightness control, adjust it so that characters are clean và well-formed. If characters are touching, use a higher (brighter) setting. If characters are separated, use a lower (darker) setting.
