Resolution is tied directly to the quality appearance of your image. Resolution is the measurement of dots per squares inch (dpi). There is a lot to process when covering this topic. This article will be for beginners and novice.
For general commercial printing, there are two common resolution requirements. 300 dpi for color and grayscale images and 1,000 dpi for black and white bitmap (mode) images. While many scanners, cameras and programs support higher resolutions and you would think the higher the resolution the better image quality, the science of printing is driven by rules of Lines Per Inch (lpi) and how technology handles processing of files.
Here's where it gets a bit sticky to understand. I'll tried to explain it has best I can while giving you some techno info.
Color and Grayscale Images.
The 300dpi resolution rule applies to color and grayscale images only.
Bitmapped Images.
In general bitmapped images should be saved at 1,000 dpi. If you have a black and white, bitmapped image, the resolution should be set to the resolution of the output device. With that said, most people do not know the resolution of the output device without talking to the print service provider. Generally, however, the accepted resolution is between 800 dpi and 1,200 dpi.
The reason behind this lays in the human eye. The human eye at 800dpi begins to process a perfect lines and curve. At 1,200 dpi, the eye cannot distinguish a higher quality.
Vector Images:
(Images created in applications such as Illustrator, CorelDraw, FreeHand, CanvasDraw)
Because of how technology works when it comes to printing, any image created within these programs are considered device independent and will print at the printers resolution thus providing excellent image quality.
Generally most print shops (as of 2008) will print anywhere from 200 to 300 lpi. Back in the 90s' it was 150 to 200 lpi.
To answer a popular question I get - If you import a color or grayscale image into a vector apllications, does it become a vector graphic - NO. It simply becomes a color or grayscale image placed within a vector file. The same rules above would still apply.
Resolution for other technologies ******************************
For web creation, the standard is 72 dpi.
For consumer level ink jet printing, generally 150 dpi prints fine. This is highly dependent on the printing device itself.
For posters and large banners, it is best to ask your print service provider. Generally I have heard resolutions ranging from 100 to 600 dpi.
For digital photos sent to Photo Processing centers, contact those centers.
Hope this helps. Richard Perez

What happens when a raster graphics is resized?

Find a High Resolution world map?
In order to find a high resolution world map, you should search for high resolution world map on an online search engine under "images." Most image websites will allow you to specify the resolution of the image.
What is canvas in computer graphics?
Canvas is the viewport or image you are working on.
What is definition of scaling in computer graphics?
In computer graphics, image scaling is the process of resizing a digital image. Scaling is a non-trivial process that involves a trade-off between efficiency, smoothness and sharpness. With bitmap graphics, as the size of an image is reduced or enlarged, the pixels which comprise the image become increasingly visible, making the image appear "soft" if pixels are averaged, or jagged if not. With vector graphics the trade-off may be in processing power for re-rendering the image, which may be noticeable as slow re-rendering with still graphics, or slower frame rate and frame skipping in computer animation.

What uses more memory bit-mapped graphics or vector graphics?
It depends on complexity of a drawn picture, but in most cases, vector graphics takes less space on a media: a bit-mapped image stores information about each pixel of an image, wille vector image stores only types of objects and parameters for further rendering.
How do you resize photo for printing?
As usual, Image > Image Size but pay attention on image resolution.
What is the recommended image resolution for high-quality printing at 300 dpi?
The recommended image resolution for high-quality printing at 300 dpi is 300 dots per inch.
What is the ideal resolution for printing an image that is 1200 pixels square at 300 dpi?
The ideal resolution for printing an image that is 1200 pixels square at 300 dpi is 4 inches by 4 inches.
What is the importance of ensuring that images are saved with a 300 ppi resolution for high-quality printing?
Saving images with a 300 ppi resolution is important for high-quality printing because it ensures that the image will have a sharp and clear appearance when printed. This resolution provides enough detail for the printer to accurately reproduce the image, resulting in a professional-looking final product.
What is the importance of ensuring that images are saved with a 300 pixels per inch resolution for high-quality printing?
Ensuring that images are saved with a 300 pixels per inch resolution is important for high-quality printing because it provides a higher level of detail and clarity in the printed image. This resolution ensures that the image will appear sharp and crisp when printed, with smooth edges and vibrant colors. Printing at a lower resolution may result in a blurry or pixelated image, reducing the overall quality of the printed material.

What is the significance of ensuring that images are saved at a resolution of 300 ppi for high-quality printing?
Saving images at a resolution of 300 ppi is important for high-quality printing because it ensures that the image will be clear and sharp when printed. A resolution of 300 ppi provides enough detail for the printer to accurately reproduce the image, resulting in a professional-looking final product.
How can I optimize the resolution of my jpeg image for high-quality printing?
To optimize the resolution of your JPEG image for high-quality printing, you should ensure that the image has a resolution of at least 300 pixels per inch (PPI) and is saved in the CMYK color mode. Additionally, make sure the image is saved at the appropriate dimensions for the desired print size to maintain sharpness and clarity.
Laser printer with 300 resolution printing?
300 DPI is a very low resolutioe resolution rating. If this is the maximum resolution for the laser printer that you are looking at, do not buy it if you need sharp (or even acceptable quality) graphics. 300 DPI is the lowest common printing resolution, and dots are easily seen when looking at an image printed. Most laser printers, however have a 300 DPI setting, along with 600 and 1,200 DPI resolutions. The resolution of a laser printer does not matter if you plan on only printing black text, as resolution does not matter in this case.
What image criteria must be checked before printing?
file size, resolution, and colormode
What is resolution in computer graphics?
The resolution of an image in computer graphics refers to the pixel density of said image. For instance, older monitors used 800x600 often times. This means that for every 4 pixels in the horizontal direction, there are 3 in the vertical. This is where the aspect ratio comes from, which for an 800x600 resolution, is 4:3. The higher the value of the resolution, the more pixels there are per area of the image or screen, which means that there is more potential for fine detail, and on most systems means a crisper image.
