Heerka Jaridawaxaa loola jeedaa tirada cabbirka muraayadda ee loo baahan yahay ka dib marka la jaro muraayadda ka hor inta aan la dhalaalin.
Qaaciddadu waa galaas u qalma oo leh cabbirka loo baahan yahay tirada x dhererka galaaska loo baahan yahay x ballaca galaaska loo baahan yahay / dhererka xaashida galaaska ceeriin / ballaca xaashida galaaska ceeriin = heerka jarista
Marka hore, waa inaan faham cad ka helnaa cabbirka caadiga ah ee xaashida galaaska ceeriin iyo inta millimitir (mm) ay tahay inay ka tagto dhererka iyo ballaca galaaska marka la jarayo:
| Dhumucda Muraayadda (mm) | Cabbirka Warqadda Muraayadda Cayriin ee Caadiga ah (mm) | Millimeter waa inuu u daayaa galaaska L. & W. (mm) |
| 0.25 | 1000 × 1200 | 0.1-0.3 |
| 0.4 | 1000 × 1500 | 0.1-0.3 |
| 0.55/0.7/1.1 | 1244.6×1092.2 | 0.1-0.3 |
| 1.0/1.1 | 1500 × 1900 | 0.1-0.5 |
| ka sarreeya 2.0 | 1830×2440 | 0.5-1.0 |
| 3.0 iyo wixii ka sareeya 3.0 | 1830×2400;2440×3660 | 0.5-1.0 |
Tusaale ahaan:
| Cabbirka Muraayadda Loo Baahan Yahay | 454x131x4mm |
| Cabbirka Warqadda Muraayadda Ceeriin ee Caadiga ah | 1836x2440mm; 2440x3660mm |
| Millimeter waa inuu u daayaa galaaska L. & W. (mm) | 0.5mm dhinac kasta |
| Cabbirka Warqadda Muraayadda Ceeriin | 1830 | 2440 | 1830 | 2440 |
| Cabbirka galaaska ee loo baahan yahay oo leh ku dar mm marka la jarayo | 454+0.5+0.5 | 131+0.5+0.5 | 131+0.5+0.5 | 454+0.5+0.5 |
| Tirada ka dib xaashida cayriin oo loo qaybiyay cabbirka galaaska loo baahan yahay | 4.02 | 18.48 | 13.86 | 5.36 |
| Wadarta tirada galaaska la xaqiijiyay | 4 × 18 = 72 xabbo | 13 × 5 = 65 xabbo | ||
| Heerka Jarida | 72x454x131/1830/2440=95% | 65x454x131/1830/2440=80% | ||
| Cabbirka Warqadda Muraayadda Ceeriin | 2240 | 3360 | 2240 | 3360 |
| Cabbirka galaaska ee loo baahan yahay oo leh ku dar mm marka la jarayo | 454+0.5+0.5 | 131+0.5+0.5 | 131+0.5+0.5 | 454+0.5+0.5 |
| Tirada ka dib xaashida cayriin oo loo qaybiyay cabbirka galaaska loo baahan yahay | 4.92 | 25.45 | 16.97 | 7.38 |
| Wadarta tirada galaaska la xaqiijiyay | 4 × 25 = 100 xabbo | 16 × 7 = 112 xabbo | ||
| Heerka Jarida | 100x454x131/2440/3660=66% | 112x454x131/2440/3660=75% | ||
Markaa si cad ayaan u ogaanay, xaashida cayriin ee 1830x2440mm ayaa ah doorashada koowaad marka la jarayo.
Ma haysaa fikrad ah sida loo tiriyo heerka dhimista?
