Whether you are using an LCD or a CRT, it is critical that you measure the display with the right tools.
The most obvious difference between a NEC's 18-inch LCD monitor and a 21-inch Mitsubishi Diamondtron 1010eCRT monitor is the clarity of the two displays. Pixels on the CRT monitor will appear slightly blurry at the edges, while pixels on the LCD monitor can maintain a high degree of clarity.
The initial use of LCD monitors may have this feeling, with the very flat display somewhat curved at the edge. But this is only a visual feeling, in fact, one of the biggest advantages of LCD displays is its linearity. A square with a side of 100mm will maintain its exact shape on the screen without any distortion. Its resolution is 90dpi instead of the standard 72dpi.
Dual-Page Dimensions This monitor is best suited to display an image size of 1,280x1,024 pixels, which can expand 100% of two A4 pages, with some room left. This feature and its high definition make it an ideal choice for page imposition.
NEC has two 18-inch monitors, one of which is a model number 1,810x. It has a screen rotation function that can turn the screen from vertical to horizontal or from horizontal to vertical. However, this rotation will be limited by cables and platforms.
The high resolution and perfect linearization of the monitor screen make it an ideal choice for page layouts and drawings using Illustrator and Free Hand, but it is also very useful when it comes to image correction and retouching using software such as Photoshop. However, it is not very ideal.
Fixed-pixel professional users need to work on screens that have been calibrated to ensure color accuracy, because that is where the problem arises. NEC's LCD display is not a rigid glass display, but a soft plastic screen, which can cause deformation during the crushing process, discoloring the local area, and the display calibration equipment can not be properly calibrated.
Another reason is that the center of the screen is slightly lighter than the edge, so that a uniform gray screen will have a slight sense of unevenness.
There are currently software calibration tools on the market, but these tools often rely on the operator's subjective decision. There will be differences in LCD display matching at least a few different locations.
One noteworthy feature of LCD displays is fixed pixels. These pixels either exist permanently or disappear permanently. Based on bright or black pixels that are fixed to these pixels, they can be most easily seen on an all-black or all-white screen. The 1,810x display has five solid bright pixels.
The fixed pixel is often not mentioned in the LCD display specification, and manufacturers tend to believe that for this size of display, the manufacturer believes that a smaller number of fixed pixels should be accepted. The five pixels are not noticeable in most cases and are not annoying even if they attract attention. So NEC's 1810x LCD display is acceptable in most cases.
In applications such as page grouping and vector drawing, the LCD display is much better than the CRT display because of its extremely accurate linearity. If you want to spell out a tabloid page, it's ideal to use a portrait display (prices £1,859+VAT), but if you don’t think it’s necessary, there’s a non-rotatable style that’s cheaper, £1,299.
The white point and gamma values ​​use NEC's 1810x to emphasize which method of correcting and processing manual images. Some software-only calibration programs claim to provide accurate calibration, but this is often considered to be the second biggest advantage of the product.
A commonly used measurement tool used in the past is the Radius ProSense meter, which is a good instrument that comes with Barco. Another X-Rite Monitor Optimiser now has the same functionality as ProSense. But ProSense can gain power by plugging into an old Mac's ADB port, and the X-Rite gets its power by plugging into a USB port. Install the driver software via the provided CD-ROM.
The operation can be started by opening a control panel named Monitor Calibrator. This process can tell whether the display has been calibrated before, and if calibrated, what is the measured white point and gamma. Before calibration, remember to close some other calibration applications, such as Adobe's Gamma Control Panel. After determining a target white point and a target gamma value, press the Calibrate button. A window will then pop up showing options for detecting the calibration instrument and two gray scales for adjusting the display for optimum contrast and brightness.
ICC display profile Next, the calibration device needs to be affixed to the screen, and then the measuring instrument starts to work. The software measures the monitor's white point, gamma, and fluorescent material, then generates an ICC monitor profile, names it, and stores it in the ColorSync folder.
This file is automatically selected in the Monitor Control Panel. The display is calibrated. But if you want to choose another different white point and gamma value to operate, the processor will re-measure each calibration setting, and then save the generated ICC profile into an appropriate name.
Also available with the X-Rite Monitor Optimiser is ColorShop, which contains a series of tools for a variety of different color-related tasks. Including: conversion colors for various color spaces; comparison colors (visual and digital); matching colors with Pantone colors; suggested complementary colors; Preview colors under different lighting conditions; and detect spectrum curves for a particular color.
Powerful physical functions In fact, the physical capabilities of the X-Rite Monitor Optimiser are so powerful that the entire calibration process cannot be further simplified and is very reliable.
It usually takes only a few minutes to perform a calibration, so calibration should be repeated often during the usual batch process.
