1, the production route is different. Photocopies are those produced through a photocopier, and photocopies are those done through imaging equipment, such as taking pictures, scanning, and so on.
2, different colors. The vast majority of photocopies are black and white, photocopies are processed through the imaging equipment out of the object can be monochrome or black and white.
3, different carriers. Copier paper is mostly thinner paper, so photocopies are mostly plain paper items. Photocopies can be ordinary paper, can also be thicker other paper, such as photo paper, etc., photocopies can also become an electronic file, easy to transmit through the network.
Expanded Information:
p>Today, the application of paper has been extended to culture and science, daily life, health care, business, national defense and industrial and agricultural production and other fields. Office paper is a piece of all office supplies are often overlooked, but because of the use of more, use frequently, it is indispensable for our daily office.
When buying, you can refer to the following performance parameters, it will help a lot. Especially for printing paper and copy paper, can fully refer to the following points to buy.
1, tensile strength: tensile strength refers to the tension of the paper or cardboard. Usually expressed in absolute tensile strength: that is, a certain width of the specimen tension (Newton); or to split length: that is, a certain width of the strip of paper under its own gravity to pull the paper off the length of the paper required (meters); or with the transverse section of the tensile strength.
That is, expressed in terms of the specimen unit cross-section of the tensile strength (Newton/m2). The higher the strength, the less likely the paper will be stretched. For example, after printing statements and forms on long lengths of paper and sticking them to the wall, if the paper has a high tensile strength, then the statement or form will not break easily and will stay in place for longer.
2, elongation: elongation refers to the paper or cardboard by a certain tension. To break the elongation of the original specimen length percentage. Elongation is an important indicator of the toughness of paper. Elongation is related to the tensile strength.
The higher the elongation, the more flexible the paper, paper is not easy to be pulled, which is similar to rubber bands. If the elongation is too low, in the use of an accident may break the paper, both for office work or economically speaking, have a negative impact.
3, tear: tear is the tear pre-cut specimen to a certain length of the force required to tear, expressed in millinewtons. The degree of tear of paper is the ability of paper and cardboard to resist balanced cracking. I do not know if you have found that some paper once there is a crack it is easy to tear in half, this is the reason that the tear degree is too low, so when you buy, you may want to take the sample to tear to see, try to choose a high degree of tear of the paper.
4, folding resistance: folding resistance refers to the paper and cardboard under a certain tension, the number of times it can withstand 180 ° of reciprocal folding. Expressed in terms of the number of reciprocal folding. Folding resistance indicates the paper's ability to withstand soft folding. It is largely related to the elongation, the user can be based on their own use will not often fold the paper to choose, but it is recommended that we buy a high degree of folding resistance of the paper.
5, tightness: tightness refers to the weight of paper and cardboard per cubic centimeter. The result is expressed in grams/cm3. Tightness is a measure of the paper or cardboard structure of the tightness of the index, is the basic nature of paper and cardboard. Tightness is actually the density of paper.
Generally speaking, the higher the tightness, the higher the tensile strength, because the cellulose that constitutes the paper is more tightly bound, then the elongation, tearing, folding resistance will also be higher. So it is a more important performance parameter, must pay more attention when buying.
