Small Paper Boxes With Lids CTP plate making workshop environmental problems

With the rapid development of printing and publishing system, manual platemaking disappeared in a short period of time. With the emergence of the computerized workflow of platemaking technology, the once-popular manual equipment also gradually disappeared. And it is because of the computer and the adoption of high technology direct publishing system, just put forward the environmental problems of plate making workshop, used in the past for manual collage, copy, open red tear film, white base and so on mountains of the situation really farewell to the workshop. Plate-making environment is a big topic, plate-making workshop environment for the health of the staff, mental state and product quality have a very important impact.

 

On a local scale, a clean and tidy working environment is the most important foundation project to reduce waste, increase productivity and reduce the rate of defective products. In some high-profile platemaking companies, not only from the overall layout pay attention to the beauty of the environment, but also from the ergonomic consideration of the state of staff work, so that each work point gives a comfortable feeling.

 

Generally people think that the workshop is to have the roar of the machine, the noise of the people, in order to show the busy production, but now on the contrary, especially the plate workshop is no longer noisy, more need to be quiet, and really to be quiet, is not an easy thing. In summary, we choose temperature, humidity, dust, odor, lighting, noise and radiation as the seven factors that affect the environment.

 

First, the right temperature makes people refreshed and the equipment works smoothly

The ups and downs of temperature not only affect people's emotions, but also the natural enemies of equipment. People in different working areas have different requirements for temperature, but the right temperature generally won't make people anxious. And the electronic and optical systems of working equipment, especially the electrical extension and photosetter, all use high-precision glass lenses. Due to the influence of temperature change, the surface of the lens is easy to produce water mist, which leads to the reduction of the definition of the electric extension scanning;

 

Phototypesetter out of the film requirements, although some manufacturers of the tolerance is very large, but from the reality, should be taken into account in its tolerance to maintain a constant value. Usually the plate workshop is divided into production center, output center and electrical branch center, the heat dissipation of the equipment is not consistent on the impact of the space, the required temperature values are also different, but they should be kept in the standard range.

 

Two, appropriate humidity can eliminate the static fatigue of people and machines

 

Humidity reflects the amount of water in the air, expressed as a percentage. The moisture content is too high, generally thought to be more than 80%, people feel more humid, the surface capacity of the machine produces water beads, especially in the machine near the ground part, is not easy to maintain, a long time easy to rust; The moisture content is too low, generally believed to be less than 40%, people feel dry, the machine operation is easy to produce static electricity, from the working state of the equipment, the upper and lower pieces of the phototypesetter is easy to be affected by static electricity, and if the maintenance is not equipped with the corresponding static electricity elimination equipment, it is easy to make the electronic circuit electrostatic breakdown phenomenon; Proofing is affected by humidity, the paper is easy to deformation, resulting in overprint is not allowed, dot expansion and other phenomena. General industrial humidifier and industrial dehumidifier to adjust, control the percentage of humidity. [next]

 

Three, the gradual accumulation of dust is the enemy of the equipment in the process of operation

Dust not only has a direct impact on human breathing, in the case of too much dust, computer and plate making equipment is vulnerable to damage. Because the dust in the workshop is very fine, affected by the exhaust and heat dissipation device of the computer and phototypeset equipment, it is easy to accumulate in the circuit board and the air inlet. If the accumulated dust is disturbed by the external temperature and humidity, it can become an instant conductor. Most of the breakdown of electronic components and short circuit board is caused by the accumulation of dust. The solution to the accumulation of dust in the workshop is to keep the ground clean and prevent the invasion of foreign dust. In addition, it is necessary to dust the computer and electronic equipment regularly and ensure the daily maintenance of the surface of all the equipment.

 

Fourth, smell is the most sensitive reaction of human beings, although the machine can not distinguish the smell, but the irritating gas can directly damage the machine

In the plate making workshop, the source of the smell is mainly three aspects: on the one hand, the various cleaning and on the draft liquid of the electrical workshop, because it does not have toxicity, and the rapid diffusion in the flowing air, not easy to affect people (but some cleaning agent in the operation process, must wear gloves, and ensure not to flow to the surface of the metal object); On the other hand is the output workshop developer and fixer, developer due to the influence of temperature and contact oxygen time and different degrees of oxidation, if the developer container is not covered strictly, the smell of the developer is easy to spread to the air, the temperature is slightly higher, condensation fog attached to the metal part of the developer, the metal part oxidation metamorphism, resulting in equipment failure. Therefore, in the process of development, we must pay attention not to be exposed for too long, especially after heating, we should pay attention not to open the lid easily; Another aspect of the smell source is the proofing department. The proofing ink and cleaning ink liquid are very pungent, but generally will not cause great harm to people, so the proofing department must pay attention to the local and overall exhaust problems. When cleaning ink, be sure to open the exhaust fan food packaging, cleaning ink and wipe ink cloth together into the closed container, as far as possible to reduce a variety of volatile odor substances exposed to the air, so effective odor resistance method is appropriate exhaust and effective closure.

 

In addition, the smell also comes from behind the high temperature device, such as the lamp of electric distribution, the high pressure device of the display, the laser tube of the phototypesetter, etc. As the temperature rises, these devices also emit odors, but because different machines use different methods of prevention, such odors generally do not cause adverse reactions.

 

Five, lighting is a big problem in the plate making workshop, it not only affects the environment of excessive packaging, more importantly, it also affects the quality of the product

Printing plate making is an industry with high requirements for lighting conditions, especially electrical division and proofing departments need to use high color rendering lighting source, in order to ensure the color restoration and adjustment of the original manuscript and accurate observation of the color of the printed product. For printing lighting, the international issued the latest ISO3664 standard, the domestic printing industry also has a set of strict evaluation standards.

 

The lighting in the plate making workshop can be divided into D65 light source and D50 light source in accordance with CIE regulations. The former is the daylight color with a color temperature of 6500k and a color rendering index of more than 90, which is suitable for observing reflected originals. The latter is the simulated daylight color with a color temperature of 5000k and a color rendering index of more than 90, which is suitable for observing transmitted originals.

 

In the color separation, proofing and output departments, if the best observation of the manuscript, must be partial or overall arrangement of standard light sources, and required to achieve the corresponding illuminance. Because both the ambient color of the sample drawing and the background color of the sample will affect the observation when viewing the sample, the color of the workshop walls and its interior facilities should be light gray or white to prevent the surrounding environment from adversely affecting the lighting.

 

Of course, to achieve higher lighting requirements, but also need a special observation platform, so as to ensure the accuracy of product color observation.

 

In short, to ensure stable and consistent quality control of observation conditions, there must be the following factors:
1. Spectral energy distribution of lighting source;

2. Luminous intensity and uniformity of lighting source;

3. Observe the environment and lighting conditions;

4. Stability of lighting environment. [next]

 

Six, the greatest harm of noise is to distract people's attention, make people prone to fatigue, at the same time, the abnormal noise of equipment is also one of the reasons for its own failure

The noise in the plate making workshop comes from the high-speed electric subdivision drum and phototypesetting drum, the fan of the exhaust device, the mechanical rolling of the press machine, and the sound of the fluorescent lamp ballast. In the midst of all the noise, the high-pitched, high-frequency sound is irritating, and the high-frequency sound is caused by the lack of oil in electronic components and machinery.

 

If the pre-press company is separated from the printing company, the equipment that produces noise is relatively less, but in the daily maintenance, it is necessary to do a good job of lubrication of the mechanical equipment, to ensure the normal work of the equipment and the quiet working environment.

 

There are also the following ways to eliminate noise:
1. Common lubricating oil;

2. Clean the ground metal;

3. Replace the noise source components.

 

Radiation is a highly technical and serious issue. But prepress platemaking equipment, including a variety of laser light sources are strictly in accordance with the relevant standards of production, and the product has the relevant certification license, so the radiation problem in the platemaking workshop is not to worry about.

 

The seven factors that exist in plate making workshop and affect the environment are analyzed above. Regarding environmental issues, we have to mention the impact of 5S activity on plate making workshop. 5S is the first letter of Romanization of five Japanese words, such as organizing, rectifying, cleaning, cleaning and cultivation. Its effectiveness is as follows:
1. Improve the corporate image;

2. Enhance employees' sense of belonging;

3. Reduce waste;

4. Security guarantee;

5. Efficiency improvement;

6. Quality assurance.

 

5S is the best solution to the environmental problems in the plate making workshop. Workshop environment should be created from people's mood, bright, clean, neat workshop naturally give employees and customers a good mood.
