In Photoshop you can easily create an prototype in one colour style and convert it to another, perhaps to become information technology prepare for a specific print task.

Convert an image to some other color mode

You lot tin can change an image from its original mode (source way) to a dissimilar mode (target mode). When y’all choose a dissimilar colour mode for an image, you permanently alter the colour values in the paradigm. For example, when y’all convert an RGB image to CMYK mode, RGB color values outside the CMYK gamut (divers past the CMYK working space setting in the
Color Settings
dialog box) are adjusted to fall within gamut. Every bit a consequence, some image information may be lost and can’t exist recovered if yous catechumen the image from CMYK back to RGB.

Before converting images, it’due south all-time to do the following:

  • Practice every bit much editing as possible in the original image way (normally RGB for images from virtually scanners or digital cameras, or CMYK for images from traditional drum scanners or imported from a Scitex system).

  • Save a backup copy before converting. Be sure to save a copy of your image that includes all layers so that you can edit the original version of the image after the conversion.

  • Flatten the file earlier converting it. The interaction of colors betwixt layer blending modes changes when the mode changes.

In nigh cases, yous’ll want to flatten a file earlier converting it. Even so, information technology isn’t required and, in some cases, it isn’t desirable (for example, when the file has vector text layers).

  1. Choose Image > Mode and the mode you want from the submenu. Modes not available for the active paradigm appear dimmed in the bill of fare.

    Images are flattened when converted to Multichannel, Bitmap, or Indexed Colour mode, because these modes do not support layers.

Catechumen an prototype to Bitmap manner

Converting an image to Bitmap mode reduces the epitome to two colors, profoundly simplifying the colour data in the paradigm and reducing its file size.

When converting a color prototype to Bitmap manner, offset catechumen it to Grayscale mode. This removes the hue and saturation information from the pixels and leaves only the effulgence values. Still, considering only a few editing options are bachelor for Bitmap mode images, it’s usually best to edit the paradigm in Grayscale mode and so catechumen information technology to Bitmap mode.

Images in Bitmap mode are 1 bit per aqueduct. You must convert a 16‑ or 32‑bits-per-aqueduct image to 8‑chip Grayscale mode before converting information technology to Bitmap mode.

    • If the image is in color, choose Prototype > Mode > Grayscale. Then choose Image > Way > Bitmap.

    • If the prototype is grayscale, choose Epitome > Manner > Bitmap.

  1. For Output, enter a value for the output resolution of the Bitmap fashion image, and choose a unit. By default, the current prototype resolution appears as both the input and the output resolutions.

  2. Choose 1 of the following bitmap conversion methods from the Use popular-up menu:


    50% Threshold

    Converts pixels with grayness values above the middle greyness level (128) to white and pixels with greyness values below that level to black. The consequence is a very loftier-contrast, black-and-white representation of the image.


    Pattern Dither

    Converts an epitome past organizing the gray levels into geometric configurations of black and white dots.


    Diffusion Dither

    Converts an image past using an error-diffusion process, starting at the pixel in the upper-left corner of the prototype. If the pixel’south value is above middle greyness (128), the pixel is changed to white—if below it, to black. Because the original pixel is rarely pure white or pure black, error is inevitably introduced. This mistake is transferred to surrounding pixels and diffused throughout the paradigm, resulting in a grainy, picture show-like texture.


    Halftone Screen

    Simulates the appearance of halftone dots in the converted image. Enter values in the Halftone Screen dialog box:

    • For Frequency, enter a value for the screen frequency, and choose a unit. Values can range from 1.000 to 999.999 for lines per inch and from 0.400 to 400.00 for lines per centimeter. Yous can enter decimal values. The screen frequency specifies the ruling of the halftone screen in lines per inch (lpi). The frequency depends on the newspaper stock and type of press used for printing. Newspapers commonly use an 85‑line screen. Magazines utilise higher resolution screens, such as 133‑lpi and 150‑lpi. Check with your impress shop for correct screen frequencies.

    • Enter a value for the screen angle in degrees from ‑180 to +180. The screen angle refers to the orientation of the screen. Continuous-tone and black-and-white halftone screens commonly apply a 45° angle.

    • For Shape, choose the dot shape you desire.

    The halftone screen becomes part of the image. If you lot print the prototype on a halftone printer, the printer will utilise its own halftone screen equally well as the halftone screen that is office of the epitome. On some printers, the effect is a moiré blueprint.


    Custom Pattern

    Simulates the appearance of a custom halftone screen in the converted epitome. Choose a design that lends itself to thickness variations, typically ane with a variety of gray shades.

    To use this choice, you first ascertain a pattern and then screen the grayscale image to apply the texture. To cover the entire paradigm, the design must be as large as the image. Otherwise, the pattern is tiled. Photoshop comes with several self-tiling patterns that can be used as halftone screen patterns.

    To fix a blackness-and-white pattern for conversion, first convert the epitome to grayscale and then utilize the Blur More filter several times. This blurring technique creates thick lines tapering from night greyness to white.

Catechumen a color photograph to Grayscale mode

  1. Open the photograph you want to convert to blackness-and-white.

  2. Cull Epitome > Mode > Grayscale.

  3. Click Discard. Photoshop converts the colors in the epitome to black, white, and shades of greyness.

    The technique above minimizes file size only discards color data and can catechumen next colors to the verbal same shade of grayness. Using a Black & White aligning layer increases file size but retains color information, letting y’all map colors to shades of gray.

Convert a Bitmap mode image to Grayscale way

You can convert a Bitmap fashion image to Grayscale mode in society to edit it. Keep in mind that a Bitmap mode image edited in Grayscale style may not look the aforementioned when y’all convert it dorsum to Bitmap mode. For example, suppose a pixel that is blackness in Bitmap mode is edited to a shade of gray in Grayscale way. When the prototype is converted back to Bitmap mode, that pixel is rendered as white if its gray value is above the middle grey value of 128.

  1. Cull Prototype > Mode > Grayscale.

  2. Enter a value between 1 and xvi for the size ratio.

    The size ratio is the factor for scaling down the image. For example, to reduce a grayscale image by 50%, enter 2 for the size ratio. If y’all enter a number greater than 1, the program averages multiple pixels in the Bitmap mode image to produce a unmarried pixel in the grayscale image. This process lets you generate multiple shades of gray from an image scanned on a 1‑bit scanner.

Catechumen a grayscale or RGB paradigm to indexed color

Converting to indexed color reduces the number of colors in the image to at most 256—the standard number of colors supported by the GIF and PNG‑viii formats and many multimedia applications. This conversion reduces file size by deleting color data from the image.

To convert to indexed color, you must start with an image that is eight bits per channel and in either Grayscale or RGB mode.

  1. Choose Image > Fashion > Indexed Color.

    All visible layers will be flattened; any hidden layers volition be discarded.

    For grayscale images, the conversion happens automatically. For RGB images, the Indexed Colour dialog box appears.

  2. Select Preview in the Indexed Color dialog box to display a preview of the changes.

  3. Specify conversion options.

Conversion options for indexed-colour images

When converting an RGB epitome to indexed colour, you can specify a number of conversion options in the Indexed Color dialog box.


Palette Blazon

A number of palette types are available for converting an image to indexed colour. For the Perceptual, Selective, and Adaptive options, you can choose using a local palette based on the current image’s colors. These are the available palette types:


Verbal

Creates a palette using the exact colors actualization in the RGB image—an choice available merely if the prototype uses 256 or fewer colors. Because the image’south palette contains all colors in the image, there is no dithering.


Arrangement (Mac OS)

Uses the Mac OS default 8‑bit palette, which is based on a uniform sampling of RGB colors.


System (Windows)

Uses the Windows system’due south default 8‑scrap palette, which is based on a uniform sampling of RGB colors.


Web

Uses the 216-color palette that web browsers, regardless of platform, use to display images on a monitor limited to 256 colors. This palette is a subset of the Mac OS 8‑scrap palette. Utilise this option to avoid browser dither when viewing images on a monitor display limited to 256 colors.


Uniform

Creates a palette past uniformly sampling colors from the RGB color cube. For case, if Photoshop takes half-dozen evenly-spaced color levels each of red, green, and blue, the combination produces a uniform palette of 216 colors (6 cubed = six ten vi x 6 = 216). The full number of colors displayed in an image corresponds to the nearest perfect cube (8, 27, 64, 125, or 216) that is less than the value in the Colors text box.


Local (Perceptual)

Creates a custom palette by giving priority to colors for which the human being heart has greater sensitivity.


Local (Selective)

Creates a color tabular array similar to the Perceptual color table, but favoring broad areas of color and the preservation of web colors. This option usually produces images with the greatest color integrity.


Local (Adaptive)

Creates a palette by sampling the colors from the spectrum appearing about commonly in the image. For example, an RGB prototype with only the colors greenish and blue produces a palette made primarily of greens and dejection. Most images concentrate colors in item areas of the spectrum. To control a palette more than precisely, commencement select a role of the image containing the colors you want to emphasize. Photoshop weights the conversion toward these colors.


Master (Perceptual)

Creates a custom palette by giving priority to colors for which the human being eye has greater sensitivity. Applies when yous have multiple documents open; takes all open documents into account.


Principal (Selective)

Creates a color table similar to the Perceptual color table, but favoring wide areas of color and the preservation of web colors. This selection unremarkably produces images with the greatest color integrity. Applies when y’all have multiple documents open; takes all open documents into account.


Master (Adaptive)

Creates a palette by sampling the colors from the spectrum appearing most commonly in the image. For example, an RGB prototype with only the colors green and blueish produces a palette made primarily of greens and blues. Near images concentrate colors in particular areas of the spectrum. To command a palette more than precisely, first select a part of the prototype containing the colors yous want to emphasize. Photoshop weights the conversion toward these colors. Applies when you have multiple documents open up; takes all open documents into account.


Custom

Creates a custom palette using the
Color Tabular array
dialog box. Either edit the color table and save it for later utilize or click Load to load a previously created color table. This pick also displays the current Adaptive palette, which is useful for previewing the colors most often used in the image.


Previous

Uses the custom palette from the previous conversion, making information technology easy to convert several images with the same custom palette.


Number Of Colors

For the Compatible, Perceptual, Selective, or Adaptive palette, y’all tin can specify the verbal number of colors to exist displayed (up to 256) by entering a value for Colors. The Colors text box controls only how the indexed color table is created. Adobe Photoshop still treats the image equally an 8‑bit, 256‑color image.


Colour Inclusion And Transparency

To specify colors to be included in the indexed color table or to specify transparency in the image, choose from the following options:


Forced

Provides options to force the inclusion of certain colors in the color tabular array.

Transparency

Specifies whether to preserve transparent areas of the image during conversion. Selecting this option adds a special index entry in the color table for transparent colors. Deselecting this choice fills transparent areas with the matte color, or with white if no matte colour is chosen.


Matte

Specifies the background color used to fill anti-aliased edges that lie adjacent to transparent areas of the image. When Transparency is selected, the matte is applied to border areas to aid blend the edges with a spider web background of the aforementioned colour. When Transparency is deselected, the matte is applied to transparent areas. Choosing None for the matte creates hard-edged transparency if Transparency is selected; otherwise, all transparent areas are filled with 100% white. The image must have transparency for the Matte options to be available.


Dithering

Unless yous’re using the Exact color table option, the color tabular array may not contain all the colors used in the paradigm. To simulate colors not in the color tabular array, you can dither the colors. Dithering mixes the pixels of the available colors to simulate the missing colors. Choose a dither choice from the menu, and enter a percentage value for the dither amount. A higher amount dithers more colors just may increase file size. You can choose from the following dither options:


None

Does not dither colors but instead uses the colour closest to the missing color. This tends to result in sharp transitions between shades of color in the image, creating a posterized upshot.


Diffusion

Uses an error-diffusion method that produces a less-structured dither than the Blueprint option. To protect colors in the paradigm that incorporate entries in the color table from beingness dithered, select Preserve Verbal Colors. This is useful for preserving fine lines and text for web images.


Pattern

Uses a halftone-like foursquare pattern to simulate any colors not in the color table.


Dissonance

Helps to reduce seam patterns along the edges of epitome slices. Choose this option if you program to slice the image for placement in an HTML table.
