Test Precision ntawm Small-Font Printing
Txawm hais tias tus qauv, qhov yuav tsum tau muaj rau txhua lub tshuab luam ntawv universal flatbed yog luam ntawv precision. Txhawm rau kuaj qhov no, luam cov ntawv hauv "Size 3" (kwv yees . 16 pt) font) hla tag nrho A4 daim ntawv siv software zoo li Photoshop. Cov zis yog suav tias tau txais yog tias cov ntawv nyeem meej, tsis muaj dab los yog qhov muag plooj. Lub xub ntiag ntawm ghosting qhia ntau dhau kev co thaum lub sij hawm luam ntawv - ib qho kev qhia ntawm cov qauv tsim tsis zoo, qhov twg cov rog tsim los ntawm kev txav ntawm lub taub hau luam tawm tsis zoo dissipated.
Kev ntsuas kev ua tau zoo ntawm Kev Luam Ntawv Rov Ua Dua
Kev sau npe tsis raug (kev sib koom ua ke) thaum rov luam tawm ua rau cov khoom pov tseg ntau dua; Yog li ntawd, xaiv lub tshuab luam ntawv nrog kev ua haujlwm ruaj khov yog qhov tseem ceeb heev. Ib txoj kev sim no suav nrog kev luam tawm daim phiaj qauv (ib lub rooj tsavxwm "tic-tac-toe") kaum zaug hauv tib txoj haujlwm. Tshawb xyuas qhov tshwm sim nrog lub iav 40x magnifying; yog tias cov kab sib tshooj zoo kawg nkaus, cov cuab yeej ua tau raws li tus qauv. Xwb, koj tuaj yeem siv qhov kev xeem sau npe zoo ib yam li cov uas siv hauv kev tshuaj ntsuam luam ntawv: ua ntej, luam ib lub xiav dot, tom qab ntawd luam cov xim liab ncaj qha rau nws. Yog tias cov xim xiav tsis pom nyob rau hauv 40x magnifying iav, lub tshuab muaj qhov siab.
Txheeb xyuas Diagonal Equality hauv Quadrilaterals
Nyob rau hauv lub tshuab luam ntawv qhov siab tshaj plaws printable cheeb tsam, luam ib daim duab plaub. Thaum luam tawm, siv tus pas ntsuas los ntsuas qhov ntev ntawm kab pheeb ces kaum. Raws li cov khoom geometric ntawm quadrilaterals, yog tias cov kab pheeb ces kaum sib npaug ntawm qhov ntev, cov duab yog lub duab plaub tiag tiag. Yog tias lawv tsis sib npaug, cov duab tsis yog duab plaub - nws tau dhau los ua lub rhombus lossis trapezoid. Yog hais tias qhov ntsuas kab pheeb ces kaum tsis sib npaug, nws qhia qhov txawv txav ntawm qhov chaw, txhais tau tias lub tshuab luam ntawv qhov tseeb tsis ua raws li cov qauv xav tau.
