Estimation of Production Time in Screen Printing Work (2)

Second, special data

You may think that not all of your printed products are suitable for wet-wet types, such as 100% cotton or white T-shirts. Several kinds of non-standard products need their own special estimation tables. For example, some workshops have only one special table, that is, there is only one exception. This is the type shown in Table 3. Other workshops may also have a variety of special tables in order to meet the needs of a variety of exceptional operations. If you have something to special deal with or something else at the production site, you also need an independent production schedule to attach to the regular table.

Table 3: Special times (in minutes)

Manual printing

Number of colors 1 color 2 colors 3 colors 4 colors 5 colors 6 colors Production time/pieces (clothing) 0.67 0.75 0.86 1.00 1.20 1.50 Setting and interruption time 12 24 36 48 60 72

Automatic printing

Color number 1 color 2 colors 3 colors 4 colors 5 colors 6 colors Production time/pieces (clothing) 0.20 0.20 0.20 0.20 0.20 0.20 Setting and interruption time 12 25 40 54 70 87
Special production requires the production of a separate table, such as the resolution of unforeseen problems or additional processing. Note: These special procedures added to the production time do not affect the set/interruption time.

The printing time, setting time, and interruption time are different for each production site. There is no point in matching or increasing the number provided in the table. The key issue is to know what your actual production data is and then use them in the estimation formula.

Third, calculate the setting and interrupt time

The set-up and interruption times are included in the previously mentioned schedule, and we now separate these figures to get more accurate figures and are consistent with the production conditions. Table 4 lists the setting/interruption times corresponding to Table 1 and Table 2 separately.

Table 4: Setting and Interrupting Time in Minutes

Manual printing

Chromatic number 1 color 2 color 3 color 4 color 5 color 6 color Setting 7 16 25 34 43 52 Interrupt 5 8 11 14 17 20

Automatic printing

Chromatic number 1 color 2 color 3 color 4 color 5 color 6 color Setting 7 17 27 37 48 60 Interrupt 5 8 13 17 22 27

The average time for setting and interruption is calculated for the particular job shown in the table. These values ​​are associated with the number of printed colors. The total time is the time used in the actual production time estimate tables (Tables 1 and 2).

The data used in this process is the average time for many jobs. Essentially, the combined time of setup and interruption represents the time a press has not been used for print production, or the time the press has not used to make money. . As a screen printer, your goal is to maximize printing time and minimize setup and interruption times.
